DETAILED DESCRIPTION

In order to make objects, technical details and advantages of theembodiments of the disclosure apparent, the technical solutions of theembodiments will be described in a clearly and fully understandable wayin connection with the drawings related to the embodiments of thedisclosure. Apparently, the described embodiments are just a part butnot all of the embodiments of the disclosure. Based on the describedembodiments herein, those skilled in the art can obtain otherembodiment(s), without any inventive work, which should be within thescope of the disclosure.

Unless otherwise defined, all the technical and scientific terms usedherein have the same meanings as commonly understood by one of ordinaryskill in the art to which the present disclosure belongs. The terms“first,” “second,” etc., which are used in the description and theclaims of the present application for disclosure, are not intended toindicate any sequence, amount or importance, but distinguish variouscomponents. Also, the terms such as “a,” “an,” etc., are not intended tolimit the amount, but indicate the existence of at least one. The terms“comprise,” “comprising,” “include,” “including,” etc., are intended tospecify that the elements or the objects stated before these termsencompass the elements or the objects and equivalents thereof listedafter these terms, but do not preclude the other elements or objects.The phrases “connect”, “connected”, etc., are not intended to define aphysical connection or mechanical connection, but may include anelectrical connection, directly or indirectly. “On,” “under,” “right,”“left” and the like are only used to indicate relative positionrelationship, and when the position of the object which is described ischanged, the relative position relationship may be changed accordingly.

Inventors of the present disclosure notice in research that in an earlystage of development of a full-screen technology, in order to implementa full-screen display, research development and design personnel placean under-screen camera and various sensors (photosensitive elements) ina notch region of a display apparatus (e.g., a display screen of amobile phone), and such display screen is called as a “notch screen”.However, the “notch screen” is not a real full-screen display, becausethe “notch screen” still occupies a large display area of the displayscreen, resulting in disadvantageous influence on user experience.

The inventors of the present disclosure further notice in research thatwith development of the full-screen technology, in order to solve theproblem of placement of an imaging sensor (e.g., a front camera) andvarious sensors (e.g., an infrared sensor) of the display apparatus, thetechnical solution of carrying out perforation in the display screen ofthe display apparatus can also be adopted, and in such a case, theimaging sensor (e.g., the front camera) and various sensors can bearranged at a position corresponding to a hole in the display screen.The hole in the display screen is positioned in a display region of thedisplay screen, and thus, the hole in the display screen is also calledas a hole in a display region (AA Hole) or an opening region of thedisplay region (called as the opening region hereafter).

FIG. 1A shows a display apparatus adopting a technical solution in whichperforation is carried out in a display screen. For example, as shown inFIG. 1A, the display screen of the display apparatus has a displayregion 910, the display region 910 includes an inactive display region914 and an active display region surrounding the inactive display region914. For example, the inactive display region 914 is not used forproviding a displayed image.

For example, as shown in FIG. 1A, an opening region (which is not shownin FIG. 1A, with reference to FIG. 1B) is positioned in the inactivedisplay region 914. For example, an imaging sensor (e.g., a frontcamera) and the inactive display region 914 of the display apparatus atleast partially overlap in a direction perpendicular to a displaysurface of the display apparatus (or in a normal direction of thedisplay surface of the display apparatus).

For example, as shown in FIG. 1A, the inactive display region 914 (theopening region) is positioned at a position of the display region 910close to an upper edge of the display region 910, and the inactivedisplay region 914 (the opening region) divides the display region 910into a first region 911, a second region 912 and a third region 913which are laid out side by side in a column direction of the displayapparatus; and the inactive display region 914 (the opening region) ispositioned in the second region 912, and the inactive display region 914(the opening region) separates the first region 911 and the third region913 from each other. For example, as shown in FIG. 1A, the size of thefirst region 911 in the column direction of the display apparatus isless than (for example, far less than) that of the third region 913 inthe column direction of the display apparatus.

The inventors of the present disclosure notice in research that in anapplication occasion (e.g., a mobile phone game) where the displayapparatus needs to be subjected to a landscape mode operation, therequirement of a user for touch performance of the first region 911(e.g., the bottom left corner of the display screen) is relatively high.Therefore, the first region 911 not only needs to have a displayfunction, but also needs to have a touch function. However, theinventors of the present disclosure further notice in research that dueto the small size of the first region 911 in the column direction of thedisplay apparatus, a portion of a touch sensor of the display apparatuspositioned in the first region 911 provides a small amount of signals,resulting in limitation to touch performance of the first region 911.

For example, the touch sensor included in the display apparatus shown inFIG. 1A includes a plurality of first touch electrodes arranged side byside in the column direction of the display apparatus and a plurality ofsecond touch electrodes arranged side by side in a row direction of thedisplay apparatus; and each of the plurality of first touch electrodesincludes a plurality of first touch sub-electrodes sequentially arrangedin the row direction of the display apparatus and electrically connectedwith each other, and each of the plurality of second touch electrodesincludes a plurality of second touch sub-electrodes sequentiallyarranged in the column direction of the display apparatus andelectrically connected with each other. For example, a display panel ofthe display apparatus further includes data lines and gate lines, thedata lines extend along the column direction of the display apparatus,and the gate lines extend along the row direction of the displayapparatus.

The inventors of the present disclosure further notice in research thatat least one of the plurality of first touch electrodes is separatedinto two portions by the opening region, at least one of the pluralityof second touch electrodes is separated into two portions by theinactive display region 914 (the opening region), and in such a case,touch driving signals and touch sensing signals cannot be normallytransmitted on the first touch electrodes and the second touchelectrodes which are respectively separated into two portions, resultingin that regions where part of the first touch electrodes and part of thesecond touch electrodes of the touch sensor are positioned are poor intouch, and user experience is influenced.

The inventors of the present disclosure further notice in research thatthere may be a plurality of opening regions in the display screen, andthe distance between the adjacent opening regions is relatively small,and thus, a touch pattern generally is not set in the region between theadjacent opening regions, so that a portion of the touch sensor includedin the display apparatus corresponding to the region between theadjacent opening regions is a touch blind region, resulting indisadvantageous influence on user experience. The inventors of thepresent disclosure further notice in research that due to the relativelysmall distance between the adjacent opening regions, even though thetouch pattern is set in the region between the adjacent opening regions,the touch sensing signal provided by the touch pattern positionedbetween the adjacent opening regions generally has a low signal-to-noiseratio, and in such a case, the portion of the touch sensor correspondingto the region between the adjacent opening regions is poor in touchperformance.

The inventors of the present disclosure further notice in research thatthe touch pattern included in the touch sensor of the display apparatusand at least partially surrounding the opening region is relativelynarrow in width (i.e., the size in the row direction of the displayapparatus is relatively small), and channel impedance (e.g., resistance)is relatively high, resulting in an increase of the difficulty that anelectric signal passes through the above-mentioned touch pattern atleast partially surrounding the opening region and a risk of poor touch,caused by electrostatic discharge, in the small-size region of theabove-mentioned touch pattern at least partially surrounding the openingregion. In addition, the touch pattern at least partially surroundingthe opening region further has a trustworthiness risk (e.g., an opencircuit risk). Exemplary illustration will be carried out below inconnection with FIG. 1B.

FIG. 1B shows a schematic diagram of a transition touch electrode 920,partially surrounding an opening region 925 and included in the touchsensor included in the display apparatus shown in FIG. 1A. For example,as shown in FIG. 1B, the opening region 925 has an arc edge portionadjacent to the transition touch electrode 920, and an arc edge portionin parallel with the arc edge portion of the opening region 925 isformed on one side of the transition touch electrode 920 close to anopening. For example, as shown in FIG. 1B, the transition touchelectrode 920 includes a transition touch sub-electrode 921 (i.e., asub-electrode with the reference sign {circle around (1)}) and atransition touch sub-electrode 922 (i.e., a sub-electrode with thereference sign {circle around (2)}) which are arranged side by side inthe column direction of the display apparatus. For example, as shown inFIG. 1B, the transition touch electrode 920 is small in size in the rowdirection of the display apparatus and particularly in a region 924 ofthe transition touch electrode 920 overlapping with a connectingsub-electrode 923. For example, the region 924 of the transition touchelectrode 920 overlapping with the connecting sub-electrode 923 isrelatively narrow in width in the row direction of the displayapparatus, and thus, the region 924 of the transition touch electrode920 overlapping with the connecting sub-electrode 923 is relatively highin channel impedance (e.g., resistance) and poor in charge conductivity;in such a case, it is more difficult for the electric signal to passthrough the region 924 of the transition touch electrode 920 overlappingwith the connecting sub-electrode 923, and the region 924 of thetransition touch electrode 920 overlapping with the connectingsub-electrode 923 has the risk of poor touch caused by electrostaticdischarge (e.g., electrostatic breakdown); and in addition, the region924 of the transition touch electrode 920 overlapping with theconnecting sub-electrode 923 also has the trustworthiness risk (e.g.,the open circuit risk).

The inventors of the present disclosure further notice in research thatthe opening region can be formed in the inactive display region 914 in alaser cutting mode. However, the inventors of the present disclosurefurther notice in research that a material for forming the touchelectrode is relatively crisp, and thus, when the opening region isformed in the inactive display region 914 in the laser cutting mode,cracks may be formed; and in addition, a subsequent laminating processmay cause further expansion of the cracks. For example, in the case thatthe cracks are expanded to enter an active touch region of the touchsensor (or a touch function region of the touch sensor), the cracks maycause poor touch. In addition, the inventors of the present disclosurefurther notice in research that the cracks may also provide a channelfor electrostatic charge conduction, then electrostatic charges enterthe active touch region (e.g., the active touch region around theopening region) of the touch sensor and are accumulated in the activetouch region of the touch sensor, and the accumulated electrostaticcharges may cause electrostatic breakdown in the active touch regionaround the opening region and then results in a poor touch function. Theinventors of the present disclosure further notice in research thatbefore emerging from a light emerging side of the display apparatus,light emitted by the display panel included in the display apparatusneeds to pass through a plurality of film layers; and an interfacebetween the adjacent film layers reflects part of the light emitted bythe display panel into the opening region. For example, in the case thata light collecting surface of the imaging sensor of the displayapparatus at least partially overlaps with the opening region, the lightreflected into the opening region is incident to the light collectingsurface of the imaging sensor, and thus results in reduction of asignal-to-noise ratio of an output image of the imaging sensor.

At least one embodiment of the present disclosure provides a touchstructure, a touch sensor and a display apparatus. Nonrestrictiveillustration will be carried out on the touch structure, the touchsensor and the display apparatus which are provided according to theembodiments of the present disclosure by several examples orembodiments, as described below, in the case of no mutual conflict,different characteristics in those specific examples or embodiments canbe combined with each other so as to obtain new examples or embodiments,and those new examples or embodiments also shall fall within the scopeof protection of the present disclosure.

FIG. 2 is a plane schematic diagram of a display apparatus provided byat least one embodiment of the present disclosure. As shown in FIG. 2,the display apparatus 03 includes any one touch sensor 01 provided by atleast one embodiment of the present disclosure.

FIG. 3A is a sectional schematic diagram of the display apparatus 03shown in FIG. 2, and the sectional schematic diagram shown in FIG. 3Acorresponds to a line AA′ shown in FIG. 2. For example, as shown in FIG.3A, the display apparatus 03 further includes an imaging sensor 511 anda display panel 512.

For example, the imaging sensor 511 may be an imaging sensor, and can beused for acquiring an image of an external environment which a lightcollecting surface of the imaging sensor 511 faces, and for example, theimaging sensor 511 may be a Complementary Metal Oxide Semiconductor(CMOS) imaging sensor or a Charge Coupled Device (CCD) imaging sensor.For example, in the case that the display apparatus 03 is a mobileterminal such as a mobile phone and a notebook computer, the imagingsensor 511 can be used for implementing a camera of the mobile terminalsuch as the mobile phone and the notebook computer; and in addition, thedisplay apparatus 03 can further include optical devices, e.g., a lens,a reflector or an optical waveguide and the like, as required so as tomodulate a related optical path. For example, the imaging sensor 511 caninclude photosensitive pixels arranged in an array. For example, eachphotosensitive pixel can include a photosensitive detector (e.g., aphotodiode and a phototransistor) and a switching transistor (e.g., aswitching transistor). For example, the photodiode can convert anoptical signal irradiated onto the photodiode into an electric signal,and the switching transistor can be electrically connected with thephotodiode so as to control whether the photodiode is in a state ofacquiring the optical signal and control time of acquiring the opticalsignal.

For example, the display panel 512 includes a display side and anon-display side which are opposite to each other, and the display panel512 is configured to execute a display operation on the display side ofthe display panel 512, i.e., the display side of the display panel 512is a light emerging side of the display panel 512 and faces a user. Thedisplay side and the non-display side are opposite in a normal directionof a display surface of the display surface 512. For example, thedisplay panel 512 may be an OLED display panel, a Quantum-dot LightEmitting Diode (QLED) display panel or other applicable display panels,and the embodiments of the present disclosure do not make any limit tothe specific type of the display panel.

For example, as shown in FIG. 3A, the touch sensor 01, the display panel512 and the imaging sensor 511 are sequentially arranged in the normaldirection of the display surface of the display apparatus 03 (e.g., in adirection perpendicular to the display panel 512), and the imagingsensor 511 is positioned on the non-display side of the display panel512.

For example, as shown in FIG. 3A, the touch sensor 01 has an openingregion 518, and the display panel 512 has an opening region 519; and theimaging sensor 511 is configured to receive and process an opticalsignal passing through the opening region 518 of the touch sensor 01 andthe opening region 519 of the display panel 512. For example, theoptical signal may be visible light, infrared light and the like.

For example, as shown in FIG. 3A, the opening region 518 of the touchsensor 01 and the opening region 519 of the display panel 512 at leastpartially overlap (e.g., fully overlap) in the normal direction of thedisplay surface of the display apparatus 03. It should be noted that inthe case that the display apparatus 03 further includes the opticaldevices for modulating the related optical path, such as the lens, thereflector or the optical waveguide and the like, the opening region 518of the touch sensor 01 and the opening region 519 of the display panel512 may not overlap in the normal direction of the display surface ofthe display apparatus 03.

In some examples, the touch sensor 01 and the display panel 512 mayrespectively have a plurality of opening regions (i.e., the displayapparatus 03 has a plurality of opening regions), and the displayapparatus 03 may also include other applicable sensors (e.g., theinfrared sensor, a distance sensor or the like); and the imaging sensor511 receives a signal via a first opening region of the plurality ofopening regions of the display apparatus 03, and other sensorsrespectively receive related signals via other opening regions of theplurality of opening regions of the display apparatus 03.

For example, as shown in FIG. 3A, the display apparatus 03 can furtherinclude a polarizer 513. For example, as shown in FIG. 3A, the polarizer513 is arranged on one side of the touch sensor 01 away from the displaypanel 512. For example, the polarizer 513 (e.g., a circular polarizer)can relieve problems of contrast deterioration and reduction of displayquality caused by reflected light (derived from reflection of thedisplay panel 512 on ambient light). For example, the polarizer 513 andthe touch sensor 01 can be in direct contact.

For example, as shown in FIG. 3A, the display apparatus 03 can furtherinclude a heat dissipating layer 516. For example, as shown in FIG. 3A,the heat dissipating layer 516 is arranged on one side of the displaypanel 512 away from the touch sensor 01.

For example, as shown in FIG. 3A, the display apparatus 03 can furtherinclude a protective layer 517 (e.g., a cover plate). For example, asshown in FIG. 3A, the protective layer 517 is positioned on one side ofthe polarizer 513 away from the touch sensor 01. For example, theprotective layer 517 can be used for protecting related film layers ofthe display apparatus from being scratched. For example, the protectivelayer 517 is a transparent substrate. For example, the transparentsubstrate may be a glass substrate, a quartz substrate, a plasticsubstrate (e.g., a polyethylene terephthalate (PET) substrate) orsubstrates made of other applicable materials.

For example, as shown in FIG. 3A, the display apparatus 03 can furtherinclude a first adhesive layer 514 and a second adhesive layer 515. Forexample, as shown in FIG. 3A, the first adhesive layer 514 is arrangedbetween the display panel 512 and the touch sensor 01, and used foradhering the display panel 512 and the touch sensor 01. The secondadhesive layer 515 is arranged between the protective layer 517 and thepolarizer 513, and used for adhering the protective layer 517 and thepolarizer 513. For example, the first adhesive layer 514 and the secondadhesive layer 515 may be optical adhesives.

For example, as shown in FIG. 3A, the polarizer 513, the heatdissipating layer 516, the first adhesive layer 514 and the secondadhesive layer 515 respectively have opening regions; the opening region518 of the touch sensor 01, the opening region 519 of the display panel512, the opening region of the polarizer 513, the opening region of theheat dissipating layer 516, the opening region of the first adhesivelayer 514 and the opening region of the second adhesive layer 515 atleast partially overlap (fully overlap) in the normal direction of thedisplay surface of the display apparatus 03.

Several points below need to be illustrated.

(1) Although the touch sensor 01, the display panel 512, the polarizer513, the heat dissipating layer 516, the first adhesive layer 514 andthe second adhesive layer 515 of the display apparatus 03 shown in FIG.3A all have the opening regions, the embodiments of the presentdisclosure are not limited thereto. For example, according to practicalapplication demands, part of the touch sensor 01, the display panel 512,the polarizer 513, the heat dissipating layer 516, the first adhesivelayer 514 and the second adhesive layer 515 of the display apparatus 03(e.g., at least one of the touch sensor 01, the first adhesive layer 514and the second adhesive layer 515) may not have the opening regions.

(2) Although the opening region 518 of the touch sensor 01, the openingregion 519 of the display panel 512, the opening region of the polarizer513, the opening region of the heat dissipating layer 516, the openingregion of the first adhesive layer 514 and the opening region of thesecond adhesive layer 515 of the display apparatus 03 shown in FIG. 3Aare all holes, the embodiments of the present disclosure are not limitedthereto. For example, according to practical application demands, atleast part of the opening region 518 of the touch sensor 01, the openingregion 519 of the display panel 512, the opening region of the polarizer513, the opening region of the heat dissipating layer 516, the openingregion of the first adhesive layer 514 and the opening region of thesecond adhesive layer 515 may be not holes, but light-transmittingregions.

For example, a production method of the display apparatus 03 shown inFIG. 3A can include step S101 to step S107 below.

In the step S101: a laminated structure of the touch sensor 01 and thepolarizer 513 is formed. For example, the touch sensor 01 can bedirectly provided on the polarizer 513, but the embodiments of thepresent disclosure are not limited thereto.

In the step S102: the first adhesive layer 514 is adhered to the surfaceof the touch sensor 01 away from the polarizer 513 (referring to FIG.3B).

In the step S103: the display panel 512 is adhered to the surface of thefirst adhesive layer 514 away from the touch sensor 01 (referring toFIG. 3C).

In the step S104: the second adhesive layer 515 is adhered to thesurface of the polarizer 513 away from the touch sensor 01 (referring toFIG. 3D).

In the step S105: perforation is carried out in a region of a laminatedstructure of the second adhesive layer 515 corresponding to the openingregion of the display apparatus 03, the polarizer 513, the touch sensor01, the first adhesive layer 514 and the display panel 512 so as to forman opening region 521 of the display apparatus 03 (referring to FIG.3E).

For example, the opening region 518 of the touch sensor 01 and theopening region 519 of the display panel 512 correspond to the openingregion 521 of the display apparatus 03. For example, in the step S105,the region of the laminated structure corresponding to the openingregion of the display apparatus 03 can be perforated by using a laser520 so as to form the opening region 521 of the display apparatus 03.

In the step S106, the protective layer 517 is formed on one side of thesecond adhesive layer 515 away from the polarizer 513.

In the step S107, the light collecting surface of the imaging sensor 511at least partially overlap with the opening region 521 of the displayapparatus 03 in the normal direction of the display surface of thedisplay apparatus 03.

In some examples, the production method of the display apparatus 03shown in FIG. 3A further includes a step S108 below.

In the step S108, the heat dissipating layer 516 is formed on thesurface of the display panel 512 away from the first adhesive layer 514.For example, the step S108 can be executed after the step S103 isexecuted and before the step S105 is executed. For example, in the casethat the production method of the display apparatus 03 further includesthe step S108, the step S105 includes: carrying out perforation on theregion of the laminated structure of the second adhesive layer 515corresponding to the opening region of the display apparatus 03, thepolarizer 513, the touch sensor 01, the first adhesive layer 514, thedisplay panel 512 and the heat dissipating layer 516 so as to form theopening region 521 of the display apparatus 03.

For example, as shown in FIG. 2, the touch sensor 01 included in thedisplay apparatus has a first region 411, a second region 412 and athird region 413 which are sequentially laid out in a second directionD2. For example, a size of the third region 413 in the second directionD2 is greater than (e.g., far greater than) that of the first region 411in the second direction D2. For example, as shown in FIG. 2, two edgesof the first region 411 in the second direction D2 respectively coincidewith an upper boundary of the touch sensor 01 and an upper boundary ofthe second region 412; and two edges of the third region 413 in thesecond direction D2 respectively coincide with a lower boundary of thesecond region 412 and a lower boundary of the touch sensor 01.

For example, the opening region of the touch sensor 01 is positioned inthe second region 412, i.e., the opening region of the touch sensor 01separates a partial region of the touch senor 01 into the first region411 and the third region 413 laid out side by side in the seconddirection D2 and spaced from each other.

For example, the display panel 512 of the display panel 03 furtherincludes data lines and gate lines, the data lines extend along thesecond direction D2, and the gate lines extend along a first directionD1 intersecting with (e.g., perpendicular to) the second direction D2.

FIG. 4 is another plane schematic diagram of a display apparatusprovided by at least one embodiment of the present disclosure. As shownin FIG. 4, the touch sensor 01 included in the display apparatus 03includes a region REG1 and a region REG2.

FIG. 5 is a schematic diagram of the partial region REG2 of the touchsensor 01 included in the display apparatus 03 shown in FIG. 4. Forexample, a structure of a region of the touch sensor 01 besides theregion REG1 and a region in parallel with the region REG1 in the firstdirection D1 is the same or similar with that of the shown partialregion REG2.

For example, as shown in FIG. 5, in the partial region REG2, the touchsensor 01 includes a plurality of first touch electrodes 11 and aplurality of second touch electrodes 12. For example, the first touchelectrode 11 may be a touch sensing electrode Rx, the second touchelectrode 12 may be a touch driving electrode Tx, but the embodiments ofthe present disclosure are not limited thereto. For example, the firsttouch electrode 11 may be the touch driving electrode Tx, and the secondtouch electrode 12 may be the touch sensing electrode Rx.

For example, as shown in FIG. 5 and FIG. 6A, the first touchsub-electrodes 111 and the second touch electrodes 12 included in thetouch sensor 01, except for the first touch sub-electrodes 111 and thesecond touch electrodes 12 located at the edges of the touch sensor 01,have parallelogram-shaped (e.g., rhombus-shaped) overall outlines. Itshould be noted that an overall outline of each of the first touchsub-electrodes 111 and the second touch electrodes 12 located at theedges of the touch sensor 01 (e.g., the lower edge of the touch sensor01) is at least part of a parallelogram (e.g., half the parallelogram)or a quadrangle.

FIG. 6B is a plane schematic diagram of a touch sensor 01 provided by atleast one embodiment of the present disclosure. For example, as shown inFIG. 6B, the touch sensor 01 further includes an intermediate region171, a peripheral region 172 at least partially surrounding theintermediate region 171, a plurality of first touch signal lines 173 anda plurality of second touch signal lines 174, and for facilitatingdescription, FIG. 6B further shows a touch circuit 175.

For example, as shown in FIG. 6B, a plurality of first touch electrodes11 and a plurality of second touch electrodes 12 are all positioned inthe intermediate region 171.

For example, as shown in FIG. 6B, the plurality of first touch signallines 173 (e.g., first ends of the plurality of first touch signallines) are respectively, electrically connected with the plurality offirst touch electrodes 11 (e.g., the first touch sub-electrodes 111 atthe outermost edges of the plurality of first touch electrodes 11 in thefirst direction D1), and extend into the peripheral region 172 from theedge of the intermediate region 171 in the first direction D1.

FIG. 6C is a sectional schematic diagram along a line HH′ shown in FIG.6B; and FIG. 6D is a sectional schematic diagram along a line II′ shownin FIG. 6B. As shown in FIG. 6C and FIG. 6D, the touch sensor 01 furtherincludes a base material 36 and a protective layer 176; the plurality offirst touch electrodes 11 and the plurality of second touch electrodes12 are positioned between the base material 36 and the protective layer176 in a direction perpendicular to the touch sensor 01; the pluralityof first touch signal lines 173 and the plurality of second touch signallines 174 are positioned on one side of the protective layer 176 awayfrom the base material 36; the plurality of first touch signal lines 173are respectively, electrically connected with the plurality of firsttouch electrodes 11 (e.g., the first touch sub-electrodes 111 includedin the plurality of first touch electrodes 11) via corresponding viaholes positioned in the protective layer 176; and the plurality ofsecond touch signal lines 174 are respectively, electrically connectedwith the plurality of second touch electrodes 12 (e.g., the second touchsub-electrodes 121 included in the plurality of second touch electrodes12) via corresponding via holes positioned in the protective layer 176.For example, the plurality of first touch signal lines 173 and theplurality of second touch signal lines 174 can be made of a metalmaterial, but the embodiments of the present disclosure are not limitedthereto. For example, the protective layer 176 can be made of atransparent insulating material.

It should be noted that in the direction perpendicular to the touchsensor 01, each of the plurality of first touch electrodes 11 and theplurality of second touch electrodes 12 can include a plurality of filmlayers, and structures of the plurality of first touch electrodes 11 andthe plurality of second touch electrodes 12 in the directionperpendicular to the touch sensor 01 can refer to FIG. 12A, FIG. 12C,FIG. 12D and the like below, and are not repeated herein for simplicity.

FIG. 7A is another schematic diagram of the partial region reg1 includedin the touch sensor 01 of the display apparatus 03 shown in FIG. 4. Itshould be noted that the partial region REG1 of the touch sensor 01 ofthe display apparatus 03 shown in FIG. 7A as well as FIGS. 8-9, FIG.14A, FIG. 24 and FIG. 30 below has the same structure as the partialregion REG1 of the touch sensor 01 of the display apparatus 03 shown inFIG. 6A, and different drawings are used for illustrating structures ofdifferent parts of the touch sensor 01 more clearly.

For example, as shown in FIG. 7A, the touch sensor 01 has a first region411, a second region 412 and a third region 413 which are sequentiallyarranged in the second direction D2. For example, as shown in FIG. 7A,the second region 412 includes an opening region 422 and an openingregion 421. For example, as shown in FIG. 7A, the opening region 422 andthe opening region 421 are spaced from each other. For example, as shownin FIG. 7A, the opening region 422 and the opening region 421 arearranged side by side in the first direction D1. For example, theopening region 422 and the opening region 421 are also positioned in theabove-mentioned intermediate region 171.

FIG. 7B is yet another plane schematic diagram of a display apparatusprovided by at least one embodiment of the present disclosure. Forexample, as shown in FIG. 7B, a center 012 of the opening region 421 anda center 011 of the touch sensor 01 do not coincide (e.g., spaced fromeach other). For example, as shown in FIG. 7B, the center 013 of theopening region 422 does not coincide with (e.g., is spaced from) thecenter 011 of the touch sensor 01.

For example, the center 011 of the touch senor 01 refers to a center ofan overall outline (e.g., an outer outline of a surface of the touchsensor 01 in parallel with the first direction D1 and the seconddirection D2). For example, the overall outline of the touch sensor 01is of a centrosymmetric structure (e.g., a rectangle structure with fourfilleted corners), and correspondingly, the center of the touch sensor01 and the center of the overall outline of the touch sensor 01 are asymmetric center of the centrosymmetric structure (e.g., the rectanglestructure with four filleted corners).

For example, the opening region 421 is of a centrosymmetric structure(e.g., a circle structure), and correspondingly, the center 012 of theopening region 421 is a symmetric center (e.g., a circle center) of thecentrosymmetric structure (e.g., the circle structure).

For example, the opening region 422 is of a centrosymmetric structure(i.e., a racetrack structure), and correspondingly, the center 013 ofthe opening region 422 is a symmetric center of the centrosymmetricstructure (i.e., the racetrack structure).

In some examples, at least one of the overall outline of the touchsensor 01, the opening region 421 and the opening region 422 is of anon-centrosymmetric structure; and in such a case, a center of thenon-centrosymmetric structure surrounds a circle center of a circle ofthe non-centrosymmetric structure having a smallest size.

For example, as shown in FIG. 6A and FIG. 7A, the plurality of firsttouch sub-electrodes 111 and the plurality of second touchsub-electrodes 121 together at least partially surround (e.g., fullysurround) the opening region 421; and the plurality of first touchsub-electrodes 111 and the plurality of second touch sub-electrodes 121together at least partially surround (e.g., fully surround) the openingregion 422.

For example, the plurality of first touch sub-electrodes 111 and theplurality of second touch sub-electrodes 121 together at least partiallysurround (e.g., fully surround) the opening region 421, which refers tothe fact that the combination structure of the plurality of first touchsub-electrodes 111 and the plurality of second touch sub-electrodes 121at least partially surrounds (e.g., fully surrounds) the opening region421; and the plurality of first touch sub-electrodes 111 and theplurality of second touch sub-electrodes 121 together at least partiallysurround (e.g., fully surround) the opening region 422, which refers toa fact that the combined structure of the plurality of first touchsub-electrodes 111 and the plurality of second touch sub-electrodes 121at least partially surrounds (e.g., fully surrounds) the opening region422.

FIG. 8 is yet another schematic diagram of the partial region REG1included in the touch sensor 01 of the display apparatus 03 shown inFIG. 4; and FIG. 9 is still a further schematic diagram of the partialregion REG1 included in the touch sensor 01 of the display apparatus 03shown in FIG. 4.

For example, as shown in FIG. 8 and FIG. 9, the touch sensor 01 furtherincludes a jumper conductor wire 21, a jumper conductor wire 22, atransition touch electrode 14, a transition touch electrode 15 and atransition touch electrode 16. For example, as shown in FIG. 7A and FIG.8, the jumper conductor wire 21, the jumper conductor wire 22, thetransition touch electrode 15 and the transition touch electrode 16 areall positioned in the second region 412. For example, at least part(e.g., all) of the transition touch electrode 14 is positioned in thesecond region 412.

For example, as shown in FIG. 8, at least one of a plurality of firsttouch electrodes 11 is separated into an electrode portion 112 and anelectrode portion 113 by the opening region 422 and the opening region421; each of the electrode portion 112 and the electrode portion 113includes at least one first touch sub-electrode 111; the electrodeportion 112 and the electrode portion 113 are positioned on both sidesof the opening region 421 in the first direction D1; the transitiontouch electrode 15 is positioned between the electrode portion 112 andthe electrode portion 113, and the electrode portion 112 and theelectrode portion 113 at least are electrically connected via jumperconductor wire 21 and the transition touch electrode 15; andcorrespondingly, at least one of the plurality of first touch electrodes11 further includes the transition touch electrode 15.

For example, as shown in FIG. 9, at least one of the plurality of secondtouch electrodes 12 is separated into two electrode portions by thesecond region 412, and two portions of at least one of the plurality ofsecond touch electrodes 12 are electrically connected via at least oneof the jumper conductor wire and the transition touch electrode.

For example, as shown in FIG. 9, one group of second touch electrodes 12in the plurality of second touch electrodes 12 (e.g., one group ofsecond touch electrodes 12 in the plurality of second touch electrodes12 includes at least one second touch electrode 12) is separated into anelectrode portion 126 and an electrode portion 127 by the second region412 (e.g., the opening region 422 in the second region 412), and each ofthe electrode portion 126 and the electrode portion 127 includes atleast one second touch sub-electrode 121; and the electrode portion 126and the electrode portion 127 are electrically connected with each othervia at least one jumper conductor wire 22.

For example, as shown in FIG. 9, one group of second touch electrodes 12in the plurality of second touch electrodes 12 (e.g., one group ofsecond touch electrodes 12 in the plurality of second touch electrodes12 includes at least one second touch electrode 12) is separated into anelectrode portion 124 and an electrode portion 125 by the second region412 (e.g., the opening region 421 in the second region 412); each of theelectrode portion 124 and the electrode portion 125 includes at leastone second touch sub-electrode 121; the transition touch electrode 16 ispositioned between the electrode portion 124 and the electrode portion125 in the second direction D2, and the electrode portion 124 and theelectrode portion 125 are electrically connected with each other via thetransition touch electrode 16; and correspondingly, each of one group ofsecond touch electrodes 12 in the plurality of second touch electrodes12 further includes the transition touch electrode 16.

For example, as shown in FIG. 9, one group of second touch electrodes 12in the plurality of second touch electrodes 12 (e.g., one group ofsecond touch electrodes 12 in the plurality of second touch electrodes12 includes at least one second touch electrode 12) is separated into anelectrode portion 122 and an electrode portion 123 by the second region412; each of the electrode portion 122 and the electrode portion 123includes at least one second touch sub-electrode 121; the electrodeportion 122 and the electrode portion 123 are positioned on both sidesof the second region 412 (e.g., the opening region 421 positioned in thesecond region 412) in the second direction D2; the transition touchelectrode 14 is positioned between the electrode portion 122 and theelectrode portion 123 in the second direction D2, and the electrodeportion 122 and the electrode portion 123 are electrically connectedwith each other via the transition touch electrode 14; andcorrespondingly, each of one group of second touch electrodes 12 in theplurality of second touch electrodes 12 further includes the transitiontouch electrode 14.

For clarity, specific structures of res of the opening region 422 andthe opening region 421, specific structures of the jumper conductor wire21, the jumper conductor wire 22, the transition touch electrode 14, thetransition touch electrode 15 and the transition touch electrode 16, aspecific connecting mode of the electrode portion 112 and the electrodeportion 113, a specific connecting mode of the electrode portion 126 andthe electrode portion 127, a specific connecting mode of the electrodeportion 124 and the electrode portion 125 and a specific connecting modeof the electrode portion 122 and the electrode portion 123 will beillustrated in detail after specific structures of the first touchsub-electrode 111 and the second touch electrode 12, the connecting modeof two adjacent first touch sub-electrodes 111 and the connecting modeof two adjacent second touch electrodes 12 are illustrated.

The specific structures of the first touch sub-electrode 111 and thesecond touch electrode 12, the connecting mode of two adjacent firsttouch sub-electrodes 111 and the connecting mode of two adjacent secondtouch electrodes 12 will be exemplarily illustrated below in connectionwith FIG. 6A to FIG. 10B.

FIG. 10A is a schematic diagram of a partial region REG3 (positioned inthe first region 411) included in the touch sensor 01 shown in FIG. 8;and FIG. 10B is a schematic diagram of a partial region REG4 (positionedin the third region 413) included in the touch sensor 01 shown in FIG.5.

For example, as shown in FIG. 6A, FIG. 10A and FIG. 10B, an area of thefirst touch sub-electrode 111 in the first region 411 is less than thatof the first touch sub-electrode 111 in the third region 413. Forexample, as shown in FIG. 6A, FIG. 10A and FIG. 10B, an area of thesecond touch sub-electrode 121 in the first region 411 is less than thatof the second touch sub-electrode 121 in the third region 413.

For example, as shown in FIG. 6A, FIG. 10A and FIG. 10B, a distance d1(refer to FIG. 10A) between the first touch sub-electrode 111 and thesecond touch sub-electrode 121 that are adjacent in the first region 411is less than that (refer to FIG. 10B) between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the third region 413. For example, the distance between thefirst touch sub-electrode 111 and the second touch sub-electrode 121that are adjacent refers to the distance d2 between two adjacent edgesof the first touch sub-electrode 111 and the second touch sub-electrode121 that are adjacent. For example, the distance between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent will be exemplarily illustrated in examples shown in FIG. 10Aand FIG. 10B, and is not repeated herein for simplicity.

For example, an amount of touch signals of the first region 411 of thetouch sensor 01 can be increased by making the distance between thefirst touch sub-electrode 111 and the second touch sub-electrode 121that are adjacent in the first region 411 less than that between thefirst touch sub-electrode 111 and the second touch sub-electrode 121that are adjacent in the third region 413.

For example, the capacitance C of a parallel-plate capacitor is directlyproportional to an expression εS/d, here ε is a constant, S represents adirectly facing area of two capacitance plates of the parallel-platecapacitor, and d represents a distance between two capacitance plates ofthe parallel-plate capacitor. For example, it can be known from theexpression above that the capacitance C is directly proportional to thearea S, and inversely proportional to the distance d. Therefore, in thecase of reducing the distance between the first touch sub-electrode 111and the second touch sub-electrode 121 that are adjacent in the firstregion 411, the capacitance between the first touch sub-electrode 111and the second touch sub-electrode 121 that are adjacent can beincreased, and correspondingly, an amount of touch signals of the firsttouch electrode 11 in the first region 411 and an amount of touchsignals of the electrode portion of the second touch electrode 12positioned in the first region 411 can be increased.

For example, by reducing the distance between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the first region 411, the amount of touch signals of thefirst touch electrode 11 in the first region 411 and the amount of touchsignals of the electrode portion of the second touch electrode 12positioned in the first region 411 can be increased in the case of notincreasing the areas of the first touch sub-electrode 111 and the secondtouch sub-electrode 121 in the first region 411, and thus, thesignal-to-noise ratio of a touch signal provided by a portion of thetouch sensor 01 positioned in the first region 411 can be increased inthe case of not reducing a touch resolution of the portion of the touchsensor 01 positioned in the first region 411.

For example, as shown in FIG. 7A and FIG. 9, at least one of theplurality of second touch electrodes 12 is separated into two electrodeportions by the second region 412. For example, as shown in FIG. 7A andFIG. 9, at least one of the plurality of second touch electrodes 12 isseparated into the electrode portion 124 and the electrode portion 125by the second region 412; and for further example, as shown in FIG. 7Aand FIG. 9, at least one of the plurality of second touch electrodes 12is separated into the electrode portion 126 and the electrode portion127 by the second region 412.

For example, as shown in FIG. 7A and FIG. 9, the electrode portion 124and the electrode portion 126 are positioned in the first region 411;and the electrode portion 125 and the electrode portion 127 arepositioned in the third region 413. For example, as shown in FIG. 7A andFIG. 9, a size of the electrode portion 124 in the second direction D2is less than that of the electrode portion 125 in the second directionD2; and a size of the electrode portion 126 in the second direction D2is less than that of the electrode portion 127 in the second directionD2.

For example, the electrode portion 124 includes all the second touchsub-electrodes 121 of the second touch electrode 12 having theabove-mentioned electrode portion 124 that are positioned in the firstregion 411; and the electrode portion 125 includes all the second touchsub-electrodes 121 of the second touch electrode 12 having theabove-mentioned electrode portion 125 that are positioned in the thirdregion 413.

For example, the electrode portion 126 includes all the second touchsub-electrodes 121 of the second touch electrode 12 with the electrodeportion 126 that are positioned in the first region 411, and the loweredge of the first region 411 corresponds to the lower edge of thelowermost second touch sub-electrode 121 included in the electrodeportion 126; and the electrode portion 127 includes all the second touchsub-electrodes 121 of the second touch electrode 12 with the electrodeportion 127 that are positioned in the third region 413, and the upperedge of the third region 413 corresponds to the upper edge of theuppermost second touch sub-electrode 121 included in the electrodeportion 127.

For example, the sizes (e.g., lengths) of the electrode portion 124 andthe electrode portion 126 in the second direction D2 are less than asize (i.e., a length) of the second touch sub-electrode 121 (i.e., thesecond touch sub-electrode 121 with the parallelogram-shaped overalloutline), positioned in the third region 413 and having the maximumsize, in the second direction D2; in such a case, the area of the firsttouch sub-electrode 111 in the first region 411 (e.g., an area of asurface in parallel with the first direction D1 and the second directionD2) is less than those of most first touch sub-electrodes 111 in thethird region 413; and the area of the second touch sub-electrode 121 inthe first region 411 is less than those of most of second touchsub-electrodes 121 in the third region 413 (e.g., the area of the secondtouch sub-electrode 121 with the maximum area).

For example, as shown in FIG. 10A and FIG. 10B, the touch sensor 01further includes a plurality of dummy electrodes 132; and each of theplurality of dummy electrodes 132 is arranged between the first touchsub-electrode 111 and the second touch sub-electrode 121 which areadjacent to each of the plurality of dummy electrodes 132.

It should be noted that the first touch sub-electrode 111 and the secondtouch sub-electrode 121 which are adjacent to the dummy electrode 132represent the first touch sub-electrode 111 and the second touchsub-electrode 121 which are the most adjacent to the dummy electrode132, and in such a case, no other first touch sub-electrodes 111 orother second touch sub-electrodes 121 are arranged between the dummy 132and the most adjacent first touch sub-electrode 111, no other firsttouch sub-electrodes 111 or other second touch sub-electrodes 121 arearranged between the dummy 132 and the most adjacent second touchsub-electrode 121, but other dummy electrodes 132 may be arrangedbetween the dummy 132 and the most adjacent first touch sub-electrode111 or between the dummy 132 and the most adjacent second touchsub-electrode 121.

For example, by arranging the dummy electrode 132 between the firsttouch sub-electrode 111 and the second touch sub-electrode 121 that areadjacent, the excessively small distance between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent and the excessively high capacitance (e.g., basic capacitance)between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent can be avoided, so that the touchsensor 01 can provide a required signal-to-noise ratio. For example, inthe case that the capacitance between the first touch sub-electrode 111and the second touch sub-electrode 121 that are adjacent is excessivelyhigh, the ratio of the capacitance change amount caused by a touchoperation to the basic capacitance is excessively small, resulting in alow signal-to-noise ratio of the touch signal caused by touch.

It should be noted that the first touch sub-electrode 111 and the secondtouch sub-electrode 121 that are adjacent represent that no other firsttouch sub-electrodes 111 or other second touch sub-electrodes 121 arearranged between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent, but the dummy electrode 132 may bearranged between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent.

For example, as shown in FIG. 10A and FIG. 10B, the number of the dummyelectrodes 132 between the first touch sub-electrode 111 and the secondtouch sub-electrode 121 that are adjacent in the first region 411 isless than that of the dummy electrodes 132 between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the third region 413.

For example, as shown in FIG. 10A and FIG. 10B, a width of the dummyelectrode 132 between the first touch sub-electrode 111 and the secondtouch sub-electrode 121 that are adjacent in the first region 411 isless than or equal to (e.g., equal to) that of the dummy electrode 132between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in the third region 413; and in sucha case, the distance between the first touch sub-electrode 111 and thesecond touch sub-electrode 121 that are adjacent in the first region 411can be reduced by reducing the number of the dummy electrodes 132between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in the first region 411.

It should be noted that the embodiments of the present disclosure is notlimited to the case of reducing the distance between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the first region 411 by reducing the number of the dummyelectrodes 132 between the first touch sub-electrode 111 and the secondtouch sub-electrode 121 that are adjacent in the first region 411, andin some examples, the distance between the first touch sub-electrode 111and the second touch sub-electrode 121 that are adjacent in the firstregion 411 can also be reduced by reducing the width of the dummyelectrode 132 between the first touch sub-electrode 111 and the secondtouch sub-electrode 121 that are adjacent in the first region 411.

For example, the number of the dummy electrode 132 between the firsttouch sub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the first region 411 is one, the number of the dummyelectrodes 132 between the first touch sub-electrode 111 and the secondtouch sub-electrode 121 that are adjacent in the third region 143 istwo, but the embodiments of the present disclosure are not limitedthereto.

For example, the dummy electrode 132 includes a plurality of electrodestrips sequentially connected. For example, widths of the plurality ofelectrode strips included in the dummy electrode 132 and sequentiallyconnected are equal to each other, i.e., the dummy electrodes 132 havethe uniform width. Exemplary illustration will be carried out below inconnection with FIG. 11.

FIG. 11 shows a plane schematic diagram of the dummy electrode 132positioned on the top left corner of FIG. 10B. As shown in FIG. 11, thedummy electrode 132 includes four electrode strips sequentiallyconnected; and the widths of the four electrode strips (e.g., the widthsin a direction perpendicular to an extending direction of the electrodestrips) respectively are W1, W2, W3 and W4. For example, W1=W2=W3=W4.

For example, the width of the dummy electrode 132 refers to the width ofthe electrode strip included in the dummy electrode 132 in the directionperpendicular to the extending direction of the electrode strip. Forexample, in the case that the widths of the plurality of electrodestrips included in the dummy electrode 132 are not exactly equal, thewidth of the dummy electrode 132 refers to a width average value of theplurality of electrode strips.

For example, as shown in FIG. 10A and FIG. 10B, the adjacent edges ofthe first touch sub-electrode 111 and the second touch sub-electrode 121that are adjacent have a consistent (e.g., the same) extending directionat any position. For example, as shown in FIG. 10A and FIG. 10B, thedistance between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent refers to the distance between theadjacent edges of the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in a direction perpendicular to theabove-mentioned consistent extending direction.

For example, as shown in FIG. 10A, the distance between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the first region 411 is d1; as shown in FIG. 10B, thedistance between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in the third region 413 is d2; andas shown in FIG. 10A and FIG. 10B, d1 is less than d2, i.e., thedistance d1 between the first touch sub-electrode 111 and the secondtouch sub-electrode 121 that are adjacent in the first region 411 isless than the distance d2 between the first touch sub-electrode 111 andthe second touch sub-electrode 121 that are adjacent in the third region413. For example, by reducing the distance d1 between the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the first region 411, the problem of reduction of thecapacitance value and the amount of touch signals caused by reduction ofthe areas of the first touch sub-electrode 111 and the second touchsub-electrode 121 in the first region 411 can be relieved.

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, thetouch sensor 01 further includes a plurality of ring-shapedsub-electrodes (e.g., can also be called as conducting rings) 134, aplurality of intermediate sub-electrodes (e.g., can also be called asbridging islands) 133, a plurality of connecting sub-electrodes 31 and aplurality of connecting sub-electrodes 32.

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, theplurality of ring-shaped sub-electrodes 134 and the plurality ofintermediate sub-electrodes 133 are positioned (e.g., only positioned)in the second region 412 and the third region 413. For example, as shownin FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, the plurality of connectingsub-electrodes 31 are positioned in the second region 412 and the thirdregion 413. For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG.10B, the plurality of connecting sub-electrodes 32 are positioned in thefirst region 411 and the third region 413.

For example, as shown in FIG. 8 and FIG. 10A, two adjacent first touchsub-electrodes 111 included in at least one first touch electrode 11 inthe first region 411 are of an integrated structure and are directly,electrically connected. For example, two adjacent first touchsub-electrodes 111 included in at least one first touch electrode 11 inthe first region 411 are formed from the same material in the samepatterning process, and there is no interface between two adjacent firsttouch sub-electrodes 111 included in at least one first touch electrode11 in the first region 411.

FIG. 12A is a sectional schematic diagram along a line BB′ shown in FIG.10A. For example, as shown in FIG. 8, FIG. 10A and FIG. 12A, both endsof each connecting sub-electrode 32 in the first region 411 arerespectively, electrically connected with two adjacent second touchsub-electrodes 121, i.e., two adjacent second touch sub-electrodes 121in the first region 411 are electrically connected with each other viathe corresponding connecting sub-electrode 32. It should be noted thattwo adjacent second touch sub-electrodes 121 represent that no otherfirst touch sub-electrodes 111 or other second touch sub-electrodes 121are arranged between the two adjacent second touch sub-electrodes 121.

For example, as shown in FIG. 10A and FIG. 12A, the second touchsub-electrode 121 and the connecting sub-electrode 32 are positioned ondifferent layers in the direction perpendicular to the touch sensor 01,and partially overlap; and in the direction perpendicular to the touchsensor 01, there is an insulating layer 35 between the second touchsub-electrode 121 and the connecting sub-electrode 32, and theconnecting sub-electrode 32 is electrically connected with the secondtouch sub-electrode 121 via a via hole in the insulating layer 35, i.e.,the touch sensor 01 is such a sensor with a conduction bridge structure.

For example, as shown in FIG. 5 and FIG. 10B, the plurality ofring-shaped sub-electrodes 134 correspond to the plurality ofintermediate sub-electrodes 133 one to one. For example, the pluralityof intermediate sub-electrodes 133 are correspondingly arranged in aspace surrounded by the plurality of ring-shaped sub-electrodes 134,i.e., each of the plurality of ring-shaped sub-electrodes 134 surroundsone corresponding intermediate sub-electrode 133.

For example, as shown in FIG. 5 and FIG. 10B, in the first direction D1,each of the ring-shaped sub-electrodes 134 is positioned between twoadjacent first touch sub-electrodes 111, and correspondingly, each ofthe plurality of intermediate sub-electrodes 133 is positioned betweentwo adjacent first touch sub-electrodes 111; in the second direction D2,each of the ring-shaped sub-electrodes 134 is positioned between twoadjacent second touch sub-electrodes 121, and correspondingly, each ofthe plurality of intermediate sub-electrodes 133 is positioned betweentwo adjacent second touch sub-electrodes 121. It should be noted thattwo adjacent first touch sub-electrodes 111 represent that no otherfirst touch sub-electrodes 111 or other second touch sub-electrodes 121are arranged between the two adjacent first touch sub-electrodes 111.

FIG. 12B is another schematic diagram of the partial region REG4included in the touch sensor 01 shown in FIG. 5; FIG. 12C is a sectionalschematic diagram along a line CC′ shown in FIG. 12B; and FIG. 12D is asectional schematic diagram along a line DD′ shown in FIG. 12B. Itshould be noted that a structure of the partial region REG4 included inthe touch sensor 01 shown in FIG. 12B is the same with that of thepartial region REG4 included in the touch sensor 01 shown in FIG. 10B,and FIG. 12B is used for showing positions of the line CC′ and the lineDD′ more clearly.

For example, as shown in FIG. 5, FIG. 10B, FIG. 12B and FIG. 12C, bothends of each connecting sub-electrode 32 in the third region 413 arerespectively, electrically connected with one corresponding second touchsub-electrode 121 and one corresponding intermediate sub-electrode 133;and correspondingly, two adjacent second touch sub-electrodes 121 in thethird region 413 are electrically connected with each other via theintermediate sub-electrode 133 (e.g., one intermediate sub-electrode133) and the connecting sub-electrode 32 (e.g., at least two connectingsub-electrodes 32).

For example, as shown in FIG. 12B and FIG. 12C, each connectingsub-electrode 32 (e.g., a first end of the connecting sub-electrode 32)in the third region 413 and the corresponding intermediate sub-electrode133 are positioned on different electrode layers in the directionperpendicular to the touch sensor 01, and partially overlap; theconnecting sub-electrode 32 (e.g., a second end of the connectingsub-electrode 32) and the corresponding second touch sub-electrode 121are positioned on different electrode layers in the directionperpendicular to the touch sensor 01, and partially overlap; and in thedirection perpendicular to the touch sensor 01, there are insulatinglayers 35 between the electrode layers where the connectingsub-electrode 32 and the intermediate sub-electrode 133 as well as thesecond touch sub-electrode 121 are positioned, the connectingsub-electrode 32 (e.g., the first end of the connecting sub-electrode32) is electrically connected with the corresponding intermediatesub-electrode 133 via a via hole in the insulating layer 35, and theconnecting sub-electrode 32 (e.g., the second end of the connectingsub-electrode 32) is electrically connected with the correspondingintermediate sub-electrode 133 via a via hole in the insulating layer35.

For example, as shown in FIG. 5, FIG. 10B, FIG. 12B and FIG. 12D, eachconnecting sub-electrode 31 in the third region 413 are electricallyconnected with one corresponding first touch sub-electrode 111 and onecorresponding ring-shaped sub-electrode 134; and correspondingly, ineach of a plurality of first touch electrodes 11 in the third region413, two adjacent first touch sub-electrodes 111 are electricallyconnected with each other via the ring-shaped sub-electrode 134 (e.g.,one ring-shaped sub-electrode 134) and the corresponding connectingsub-electrode 31 (e.g., at least two connecting sub-electrodes 31)between two adjacent first touch sub-electrodes 111.

For example, as shown in FIG. 12B and FIG. 12D, each connectingsub-electrode 31 (e.g., a first end of the connecting sub-electrode 31)in the third region 413 and the corresponding intermediate sub-electrode133 are positioned on different electrode layers in the directionperpendicular to the touch sensor 01, and partially overlap; and in thedirection perpendicular to the touch sensor 01, there is an insulatinglayer 35 between the connecting sub-electrode 31 and the correspondingintermediate sub-electrode 133, and the connecting sub-electrode 31 iselectrically connected with the corresponding intermediate sub-electrode133 via a via hole in the insulating layer 35. For example, as shown inFIG. 12B and FIG. 12D, each connecting sub-electrode 31 (e.g., a secondend of the connecting sub-electrode 31) in the third region 413 and thecorresponding first touch sub-electrode 111 are positioned on differentelectrode layers in the direction perpendicular to the touch sensor 01;and in the direction perpendicular to the touch sensor 01, there is aninsulating layer 35 between the connecting sub-electrode 31 and thecorresponding first touch sub-electrode 111, and the connectingsub-electrode 31 is electrically connected with the corresponding firsttouch sub-electrode 111 via a via hole in the insulating layer 35.

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, byenabling two adjacent second touch sub-electrodes 121 in the firstregion 411 to be electrically connected with each other directly via thecorresponding connecting sub-electrode 32, the ring-shaped sub-electrode134 and the intermediate sub-electrode 133 can be not arranged betweenthe two adjacent second touch sub-electrodes 121 in the first region411, so that the distance between the two adjacent second touchsub-electrodes 121 in the first region 411 in the second direction D2can be reduced (compared to the distance between two adjacent secondtouch sub-electrodes 121 in the third region 413).

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, thedistance between two adjacent second touch sub-electrodes 121 in thefirst region 411 in the second direction D2 is less than that betweentwo adjacent second touch sub-electrodes 121 in the third region 413 inthe second direction D2. For example, the distance between two adjacentsecond touch sub-electrodes 121 in the second direction D2 refers to thedistance between a virtual straight line in parallel with the seconddirection D2 and a virtual connecting line of two intersection points oftwo adjacent sides of two adjacent second touch sub-electrodes 121 inthe second direction D2. For example, as shown in FIG. 10A, the distancebetween two adjacent second touch sub-electrodes 121 in the first region411 in the second direction D2 is d3; and as shown in FIG. 10B, thedistance between two adjacent second touch sub-electrodes 121 in thethird region 413 in the second direction D2 is d4, and d3 is less thand4.

For example, by reducing the distance between two adjacent second touchsub-electrodes 121 in the first region 411 in the second direction D2,more spaces of the first region 411 can be used for arranging the secondtouch sub-electrode 121 and the first touch sub-electrode 111, and insuch a case, the areas (e.g., active electrode areas) of the secondtouch sub-electrode 121 and the first touch sub-electrode 111 can beincreased in the case of not reducing the touch resolution of theportion of the touch sensor 01 positioned in the first region 411, sothat the signal-to-noise ratio of the touch signal provided by theportion of the touch sensor 01 positioned in the first region 411 can befurther increased.

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, twoadjacent second touch sub-electrodes 121 in the first region 411 areelectrically connected via a corresponding first number of connectingsub-electrodes 32; and two adjacent second touch sub-electrodes 121 inthe third region 413 are electrically connected via a correspondingsecond number of connecting sub-electrodes 32. For example, as shown inFIG. 5, FIG. 8, FIG. 10A and FIG. 10B, the first number is less than thesecond number. For example, two adjacent first touch sub-electrodes 111in the third region 413 are electrically connected via a correspondingthird number of connecting sub-electrodes 31. For example, the secondnumber is equal to the third number, but the embodiments of the presentdisclosure are not limited thereto.

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, thefirst number is two, and both the second number and the third number are4 (i.e., a two-bridge type touch bridge solution is adopted in the firstregion 411, and an eight-bridge type touch bridge solution is adopted inthe third region 413), so that reliability of the touch sensor 01 can bepromoted. It should be noted that the first number is not limited to 2,the second number is not limited to 4, and according to practicalapplication demands, the first number and the second number can also berespectively set as one or two or set as other proper number, which isnot repeated herein for simplicity.

For example, as shown in FIG. 10A, two adjacent second touchsub-electrodes 121 in the first region 411 are electrically connectedvia two corresponding connecting sub-electrodes 32 arranged side by sidein the first direction D1 (e.g., in parallel with each other), but theembodiments of the present disclosure are not limited thereto.

For example, as shown in FIG. 10B, in the plurality of first touchelectrodes 11 in the third region 413, two adjacent first touchsub-electrodes 111 are electrically connected with each other via thering-shaped sub-electrode 134 between the two adjacent first touchelectrodes 111 and the corresponding third number of connectingsub-electrodes 31; the third number is equal to 4; the correspondingthird number of connecting sub-electrodes 31 are arranged in two rowsand two columns; two connecting sub-electrodes 32 in the same column inthe corresponding third number of connecting sub-electrodes 31 are usedfor electrically connecting one corresponding first touch sub-electrode111 and one corresponding ring-shaped sub-electrode 134; extendingdirections of two connecting sub-electrodes 32 in the same column in thecorresponding third number of connecting sub-electrodes 31 intersectwith each other; and extending directions of two connectingsub-electrodes 32 in the same row in the corresponding third number ofconnecting sub-electrodes 31 intersect with each other. For example, asshown in FIG. 9 and FIG. 10B, each of the plurality of first touchelectrodes 11 includes an applicable number of connecting sub-electrodes31.

For example, as shown in FIG. 10B, two adjacent second touchsub-electrodes 121 in the third region 413 are electrically connectedvia four corresponding connecting sub-electrodes 32; the fourcorresponding connecting sub-electrodes 32 are arranged in two rows andtwo columns; two connecting sub-electrodes 32 in the same row in thefour corresponding connecting sub-electrodes 32 are electricallyconnected with one corresponding second touch sub-electrode 121 and onecorresponding intermediate sub-electrode 133; extending directions oftwo connecting sub-electrodes 32 in the same column in the fourcorresponding connecting sub-electrodes 32 intersect with each other;and extending directions of two connecting sub-electrodes 32 in the samerow in the four corresponding connecting sub-electrodes 32 intersectwith each other.

For example, as shown in FIG. 10A and FIG. 10B, an area of eachconnecting sub-electrode 32 in the first region 411 is greater than thatof each connecting sub-electrode 32 in the third region 413. Forexample, as shown in FIG. 10A and FIG. 10B, a length of each connectingsub-electrode 32 in the first region 411 is greater than that of eachconnecting sub-electrode 32 in the third region 413. For example, asshown in FIG. 10A and FIG. 10B, a width of each connecting sub-electrode32 in the first region 411 is greater than that of each connectingsub-electrode 32 the third region 413.

For example, as shown in FIG. 9, FIG. 10A and FIG. 10B, each of theplurality of second touch electrodes 12 includes the applicable numberof connecting sub-electrodes 32.

FIG. 13 is a schematic diagram of a laminated structure of the touchsensor 01 included in the display apparatus 03 shown in FIG. 2. As shownin FIG. 13, the touch sensor 01 includes a first electrode layer 10, aninsulating layer 35 and a connecting electrode layer 20 sequentiallyarranged in a direction perpendicular to the touch sensor 01 (e.g., thenormal direction of the display surface of the display apparatus).

For example, as shown in FIG. 12A, FIG. 12C, FIG. 12D and FIG. 13, theplurality of first touch sub-electrodes 111, the plurality of secondtouch sub-electrodes 121, the plurality of ring-shaped sub-electrodes134 and the plurality of intermediate sub-electrodes 133 are allpositioned in the same electrode layer (e.g., the first electrode layer10), and are in contact with the same film layer (e.g., the insulatinglayer 35); and the plurality of connecting sub-electrodes 31 and theplurality of connecting sub-electrodes 32 are both positioned in thesame electrode layer (e.g., the connecting electrode layer 20), and arein contact with the same film layer (e.g., the insulating layer 35).

For example, the first electrode layer 10 is made of a transparentconducting material. For example, the transparent conducting materialcan be selected from transparent metal oxide such as Indium Tin Oxide(ITO), Indium Zinc Oxide (MO) or the like. For example, the connectingelectrode layer 20 is made of a transparent conducting material or ametal material. For example, the metal material can be selected fromsilver (Ag), aluminum (Al), molybdenum (Mo), titanium (Ti), aluminumalloy or other suitable materials. For example, the insulating layer 35can include an inorganic insulating material or an organic insulatingmaterial. For example, the inorganic insulating material may be one or arandom combination of silicon oxide, silicon nitride and siliconoxynitride; and the organic insulating material may be one or a randomcombination of polyimide, polyphthalimide, polyphthalamide, acrylicresin, benzocyclobutene or phenolic resin.

For example, as shown in FIG. 13, the touch sensor 01 can furtherinclude a second electrode layer 30. For example, the second electrodelayer 30 includes the above-mentioned jumper conductor wire 21 and theabove-mentioned jumper conductor wire 22 (refer to FIG. 20B below). Forexample, as shown in FIG. 13, the second electrode layer 30, forexample, is arranged between the first electrode layer 10 and theinsulating layer 35. For example, the second electrode layer 30 (e.g., asurface of the second electrode layer 30) and the first electrode layer10 (e.g., a surface of the first electrode layer 10) are in directcontact, so that a manufacturing process of the touch sensor 01 can besimplified. For example, the second electrode layer 30 is made of ametal material.

For example, as shown in FIG. 13, the touch sensor 01 can furtherinclude a transparent base material 36. For example, the transparentbase material 36 is arranged on one side of the first electrode layer 10away from the connecting electrode layer 20. For example, thetransparent base material 36 can be made of Cyclo Olefin Polymer (COP)or other applicable materials.

In some examples, the touch sensor 01 shown in FIG. 13 can furtherinclude the protective layer 176 (which is not shown in FIG. 13) shownin FIG. 6C and FIG. 6D, and the protective layer 176 is positioned onone side of the connecting electrode layer 20 away from the transparentbase material 36 (e.g., on the surface of the connecting electrode layer20 away from the transparent base material 36).

It should be noted that in some examples, the plurality of first touchsub-electrodes 111, the plurality of second touch sub-electrodes 121,the plurality of ring-shaped sub-electrodes 134 and the plurality ofintermediate sub-electrodes 133 are all positioned on a plurality ofelectrode layers, which is not repeated herein for simplicity.

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, edges ofthe first touch sub-electrode 111 and the second touch sub-electrode 121that are adjacent respectively have corresponding bent structures 131;the first touch sub-electrode 111 and the second touch sub-electrode 121that are adjacent in the first region 411 intersect with each other andhave a first intersecting depth; the first touch sub-electrode 111 andthe second touch sub-electrode 121 that are adjacent in the third region413 intersect with each other and have a second intersecting depth; andthe first intersecting depth is greater than the second intersectingdepth.

For example, as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, in thefirst touch sub-electrode 111 and second touch sub-electrode 121, bothof which are adjacent to each other, the edge of the first touchsub-electrode 111 and the edge of the second touch sub-electrode 121have the same extending direction (at a random position). For example,as shown in FIG. 5, FIG. 8, FIG. 10A and FIG. 10B, in the first touchsub-electrode 111 and second touch sub-electrode 121, both of which areadjacent to each other, the edge of the first touch sub-electrode 111includes a plurality of first line segments L1 (e.g., straight linesegments) sequentially connected, and the edge of the second touchsub-electrode 121 includes a plurality of second line segments L2 (e.g.,straight line segments) sequentially connected; the plurality of firstline segments L1 and the plurality of second line segments L2 correspondone to one and are opposite to each other; each of the plurality offirst line segments L1 has the same extending direction with thecorresponding second line segment L2; two adjacent (e.g., any twoadjacent) first line segments L1 intersect with each other, and twoadjacent (e.g., any two adjacent) second line segments L2 intersect witheach other; and the first line segment L1 and second line segment L2that are adjacent to each other (e.g., any two adjacent) are in parallelwith each other.

For example, as shown in FIG. 10A and FIG. 10B, an intersecting depth ofthe first touch sub-electrode 111 and the second touch sub-electrode 121refers to: in two adjacent first line segments, a distance from anintersection point of two first line segments to a virtual connectingline between an end point of the first one of the first line segments,which is not in contact with the second one of the first line segments,and an end point of the second one of the first line segments, which isnot in contact with the first one of the first line segments; the firstintersecting depth cd1 refers to the maximum value of the intersectingdepth of the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in the first region 411; the secondintersecting depth cd2 refers to the maximum value of the intersectingdepth of the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in the third region 413; and asshown in FIG. 10A and FIG. 10B, cdl is less than cd2.

For example, by making the first intersecting depth cd1 greater than thesecond intersecting depth cd2, an intersecting area of the first touchsub-electrode 111 and the second touch sub-electrode 121 that areadjacent in the first region 411 can be increased, and thus, the amountof touch signals of the first region 411 can be increased.

It should be noted that although the touch sub-electrode 111 and thetouch sub-electrode 121 of the touch sensor 01 of the display apparatus03 shown in FIG. 6A to FIG. 11, FIG. 12A to FIG. 12D and other relateddrawings are both made of the transparent conductive materials, theembodiments of the present disclosure are not limited thereto. Forexample, according to practical application demands, at least one of thetouch sub-electrode 111 and the touch sub-electrode 121 of the touchsensor 01 of the display apparatus 03 shown in FIG. 6A to FIG. 11, FIG.12A to FIG. 12D and other related drawings can also be made of a metalmesh.

It should be noted that although the first region 411 of the touchsensor 01 of the display apparatus 03 shown in FIG. 6A to FIG. 11, FIG.12A to FIG. 12D and other related drawings simultaneously adopt threedesigns below to increase the amount of touch signals of the firstregion 411: the two-bridge design, the increase of the intersectingdepth of the adjacent touch sub-electrode 111 and touch sub-electrode121 and reduction of the distance between the adjacent touchsub-electrode 111 and touch sub-electrode 121 (e.g., reduction of thenumber of the dummy electrodes between the adjacent touch sub-electrode111 and touch sub-electrode 121), the embodiments of the presentdisclosure are not limited thereto. For example, according to practicalapplication demands, the first region 411 of the touch sensor 01 of thedisplay apparatus 03 shown in FIG. 6A to FIG. 11, FIG. 12A to FIG. 12Dand other related drawings can also adopt any one or any two of thethree designs above.

In an example, the amount of touch signals of the first region 411 canbe increased only by adopting the two-bridge design. In theabove-mentioned example, the touch sensor includes the opening region421, a plurality of first touch electrodes 11, a plurality of secondtouch electrodes 12 and a plurality of connecting sub-electrodes 32. Thecenter of the opening region 421 and the center of the touch sensor donot coincide; the plurality of first touch electrodes 11 respectivelyextend along the first direction D1, and at least one of the pluralityof first touch electrodes 11 includes a plurality of first touchsub-electrodes 111 arranged side by side in the first direction D1 andelectrically connected with each other; the plurality of second touchelectrodes 12 respectively extend along the second direction D2intersecting with the first direction D1, and at least one of theplurality of second touch electrodes 12 includes a plurality of secondtouch sub-electrodes 121 arranged side by side in the second directionD2 and electrically connected with each other; the plurality of firsttouch electrodes 11 are arranged side by side along the second directionD2, and the plurality of second touch electrodes 12 are arranged side byside along the first direction D1; the plurality of first touchsub-electrodes 111 and the plurality of second touch sub-electrodes 121together at least partially surround the opening region 421; the touchsensor 01 has the first region 411, the second region 412 and the thirdregion 413 which are sequentially laid out in the second direction D2;the opening region 421 is positioned in the second region 412; theadjacent second touch sub-electrodes 121 in the first region 411 areelectrically connected via a corresponding first number of connectingsub-electrodes 32; and the adjacent second touch sub-electrodes 121 inthe third region 413 are electrically connected via a correspondingsecond number of connecting sub-electrodes 32, and the second number isgreater than the first number.

In another example, the amount of touch signals of the first region 411can be increased only by reducing the distance between the adjacenttouch sub-electrode 111 and touch sub-electrode 121 (e.g., reducing thenumber of the dummy electrodes between the adjacent touch sub-electrode111 and touch sub-electrode 121). In the above-mentioned anotherexamples, the touch sensor includes the opening region 421, a pluralityof first touch electrodes 11 and a plurality of second touch electrodes12. The center of the opening region 421 and the center of the touchsensor do not coincide; the plurality of first touch electrodes 11respectively extend along the first direction D1, and at least one ofthe plurality of first touch electrodes 11 includes a plurality of firsttouch sub-electrodes 111 arranged side by side in the first direction D1and electrically connected with each other; the plurality of secondtouch electrodes 12 respectively extend along the second direction D2intersecting with the first direction D1, and at least one of theplurality of second touch electrodes 12 includes a plurality of secondtouch sub-electrodes 121 arranged side by side in the second directionD2 and electrically connected with each other; the plurality of firsttouch electrodes 11 are arranged side by side along the second directionD2, and the plurality of second touch electrodes 12 are arranged side byside along the first direction D1; the plurality of first touchsub-electrodes 111 and the plurality of second touch sub-electrodes 121together at least partially surround the opening region 421; the touchsensor 01 has the first region 411, the second region 412 and the thirdregion 413 which are sequentially laid out in the second direction D2;the opening region 421 is positioned in the second region 412; and adistance between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in the first region 411 is less thanthat between the first touch sub-electrode 111 and the second touchsub-electrode 121 that are adjacent in the third region 413.

In yet another example, the touch sensor 01 provided by at least oneembodiment of the present disclosure may also not adopt the technicalsolution of increasing the amount of touch signals of the first region411, but just both the first region 411 and the third region 413 on bothsides of the opening region 421 include the first touch sub-electrodes111 and the second touch sub-electrodes 121. In the above-mentioned yetanother example, the touch sensor includes the opening region 421, aplurality of first touch electrodes 11 and a plurality of second touchelectrodes 12. The center 012 of the opening region 421 and the center011 of the touch sensor do not coincide; the plurality of first touchelectrodes 11 respectively extend along the first direction D1, and atleast one of the plurality of first touch electrodes 11 includes aplurality of first touch sub-electrodes 111 arranged side by side in thefirst direction D1 and electrically connected with each other; theplurality of second touch electrodes 12 respectively extend along thesecond direction D2 intersecting with the first direction D1, and atleast one of the plurality of second touch electrodes 12 includes aplurality of second touch sub-electrodes 121 arranged side by side inthe second direction D2 and electrically connected with each other; theplurality of first touch electrodes 11 are arranged side by side alongthe second direction D2, and the plurality of second touch electrodes 12are arranged side by side along the first direction D1; the plurality offirst touch sub-electrodes 111 and the plurality of second touchsub-electrodes 121 together at least partially surround the openingregion 421; the touch sensor 01 has the first region 411, the secondregion 412 and the third region 413 which are sequentially laid out inthe second direction D2; the opening region 421 is positioned in thesecond region 412; and an area of the first touch sub-electrode 111 inthe first region 411 is less than that of the first touch sub-electrode111 in the third region 413, or an area of the second touchsub-electrode 121 in the first region 411 is less than that of thesecond touch sub-electrode 121 in the third region 413. For example, byenabling the first region 411 and the third region 413 on both sides ofthe opening region 421 to both include the first touch sub-electrodes111 and the second touch sub-electrodes 121, an active touch area of thetouch sensor can be increased, so that user experience can be improved.

In some examples, the touch sensor 01 includes the opening region 422, aplurality of first touch electrodes 11, a plurality of second touchelectrodes 12, at least one jumper conductor wire 21, and at least onefirst conducting electrode 211. The center of the opening region 422 andthe center of the touch sensor 01 do not coincide; the plurality offirst touch electrodes 11 respectively extend along the first directionD1, and at least one of the plurality of first touch electrodes 11includes a plurality of first touch sub-electrodes 111 arranged side byside in the first direction D1 and electrically connected with eachother; the plurality of second touch electrodes 12 respectively extendalong the second direction D2 intersecting with the first direction D1,and at least one of the plurality of second touch electrodes 12 includesa plurality of second touch sub-electrodes 121 arranged side by side inthe second direction D2 and electrically connected with each other; theplurality of first touch electrodes 11 are arranged side by side alongthe second direction D2, and the plurality of second touch electrodes 12are arranged side by side along the first direction D1; the plurality offirst touch sub-electrodes 111 and the plurality of second touchsub-electrodes 121 together at least partially surround the openingregion 422; at least one of the plurality of first touch electrodes 11is separated into the electrode portion 112 and the electrode portion113 by the opening region 422; each of the electrode portion 112 and theelectrode portion 113 includes at least one first touch sub-electrode111; the electrode portion 112 and the electrode portion 113 arepositioned on both sides of the opening region 422 in the firstdirection D1; at least one jumper conductor wire 21 at least partiallysurrounds the opening region 422; at least one first conductingelectrode 211 is respectively and directly connected with the endportion of at least one jumper conductor wire 21 close to the electrodeportion 112; the line width of at least one of at least one jumperconductor wire 21 is less than the side length of such a side (connectedwith at least one of at least one jumper conductor wire 21) of the firstconducting electrode 211 connected with the at least one of at least onejumper conductor wire 21; and the electrode portion 112 and theelectrode portion 113 are at least electrically connected with eachother via the corresponding connecting sub-electrode 31, thecorresponding first conducting electrode 211 and the correspondingjumper conductor wire 21.

For example, by arranging at least one first jumper conductor wire 21,two portions of the first touch electrode 11 that are separated by theopening region can be electrically connected with each other, so thatpoor touch, caused by the opening region, in a region where part of thefirst touch electrodes 11 are positioned can be avoided.

For example, by arranging the first conducting electrode 211 and makingthe size (the side length) of the first conducting electrode greaterthan the line width of the jumper conductor wire 21, the electrodeportion 112 and the jumper conductor wire 21 can be electricallyconnected better.

In some examples, the touch sensor 01 further includes at least onefirst jumper conductor wire 22. For example, by arranging at least onefirst jumper conductor wire 22, two portions of the second touchelectrode 12 that are separated by the opening region can beelectrically connected with each other, so that poor touch, caused bythe opening region, in a region where part of the second touchelectrodes 12 are positioned, can be avoided.

The connecting mode of the second touch electrode 12 separated into twoportions (e.g., the electrode portion 126 and the electrode portion 127)by the opening region 422 will be exemplarily illustrated in connectionwith FIG. 14A to FIG. 19; and after that, the connecting mode of thefirst touch electrode 11 separated into two portions (e.g., theelectrode portion 112 and the electrode portion 113) by the openingregion 422 will be exemplarily illustrated.

FIG. 14A is one additional schematic diagram of the partial region REG1included in the touch sensor 01 of the display apparatus 03 shown inFIG. 4; and FIG. 14B is a schematic diagram for showing that twoelectrode portions of the first touch electrode 11 provided by at leastone embodiment of the present disclosure that are separated by theopening region 422 are electrically connected via the jumper conductorwire. FIG. 15 is a plane schematic diagram of a partial region REGL1 ofthe touch sensor 01 shown in FIG. 14A; FIG. 16 is a plane schematicdiagram of a partial region REGL3 of the touch sensor 01 shown in FIG.15; FIG. 17 is a plane schematic diagram of a partial region REGL2 ofthe touch sensor 01 shown in FIG. 14A; FIG. 18 is a plane schematicdiagram of a partial region REGL4 of the touch sensor 01 shown in FIG.17; and FIG. 19 is a plane schematic diagram of a partial region REGL5of the touch sensor 01 shown in FIG. 17.

For example, as shown in FIG. 14A to FIG. 19, one of the plurality ofsecond touch electrodes 12 is separated into an electrode portion 126_1and an electrode portion 127_1 by the opening region 422, and anotherone of the plurality of second touch electrodes 12 is separated into anelectrode portion 126_2 and an electrode portion 127_2 by the openingregion 422; at least one jumper conductor wire 22 includes a pluralityof jumper conductor wires 22 (e.g., a jumper conductor wire 22_1 and ajumper conductor wire 22_2) arranged side by side; the electrode portion126_1 and the electrode portion 127_1 are electrically connected witheach other via the jumper conductor wire 22_1; and the electrode portion126_2 and the electrode portion 127_2 are electrically connected witheach other via the jumper conductor wire 22_2.

For example, as shown in FIG. 14A to FIG. 19, both ends of the jumperconductor wire 22_1 are respectively in direct contact with theelectrode portion 126_1 (e.g., at least one second touch sub-electrode121 included in the electrode portion 126_1) and the electrode portion127_1 (e.g., at least one second touch sub-electrode 121 included in theelectrode portion 127_1), so that a signal on the electrode portion126_1 can be transferred to the electrode portion 127_1 via the jumperconductor wire 22_1.

For example, as shown in FIG. 14A to FIG. 19, both ends of the jumperconductor wire 22_2 are respectively in direct contact with theelectrode portion 126_2 (e.g., at least one second touch sub-electrode121 included in the electrode portion 126_2) and the electrode portion127_2 (e.g., at least one second touch sub-electrode 121 included in theelectrode portion 127_2), so that a signal on the electrode portion126_2 can be transferred to the electrode portion 127_2 via the jumperconductor wire 22_2.

For example, as shown in FIG. 14A to FIG. 19, at least one second touchsub-electrode 121 included in the electrode portion 126 and thecorresponding jumper conductor wire 22 are positioned on differentelectrode layers in the direction perpendicular to the touch sensor 01,and the end portion of the corresponding jumper conductor wire 22 closeto the electrode portion 126 is in direct contact with the surface of atleast one second touch sub-electrode 121 included in the electrodeportion 126; and at least one second touch sub-electrode 121 included inthe electrode portion 127 and the corresponding jumper conductor wire 22are positioned on different electrode layers in the directionperpendicular to the touch sensor 01, and the end portion of thecorresponding jumper conductor wire 22 close to the electrode portion127 is in direct contact with the surface of at least one second touchsub-electrode 121 included in the electrode portion 127.

For example, at least one jumper conductor wire 22 (e.g., the jumperconductor wire 22_1 and the jumper conductor wire 22_2) can be made of ametal material, and in such a case, the channel impedance (e.g.,resistance) between the electrode portion 126 and the electrode portion127 can be reduced, so that the electric signal can pass through the atleast one jumper conductor wire 22 more easily, and thus, touchperformance can be improved.

For example, as shown in FIG. 14A to FIG. 19, a length (e.g., a physicallength) of the jumper conductor wire 22_2 is greater than that of thejumper conductor wire 22_1. For example, as shown in FIG. 14A to FIG.16, a partial region of the jumper conductor wire 22_2 and the jumperconductor wire 22_1 coincide with each other in the second direction D2;compared to the jumper conductor wire 22_1, the portion of the jumperconductor wire 22_2 coinciding with the jumper conductor wire 22_1 inthe second direction D2 is closer to the center of the opening region422 in the second direction D2, i.e., the length of the jumper conductorwire 22 is negatively correlated with a distance, between the jumperconductor wire 22 and the center of the opening region 422 in the seconddirection D2, in the second direction D2; and the length of jumperconductor wire 22 is negatively correlated with a distance, between thejumper conductor wire 22 and the center of the opening region 422 in thefirst direction D1, in the first direction D1.

It should be noted that in order to clearly show the jumper conductorwire for electrically connecting two electrode portions of the firsttouch electrode 11 that are separated by the opening region 422, FIG.14B magnifies a partial structure (e.g., magnifies the line width of thejumper conductor wire), and thus, FIG. 14B is merely used for showingthe jumper conductor wire 22 for electrically connecting two electrodeportions of the first touch electrode 11 that are separated by theopening region 422 and an arranging mode of a plurality of jumperconductor wires 22, but is not intended to limit the shape of the jumperconductor wire 22, the shape of the second touch sub-electrode 121 andthe like.

For example, as shown in FIG. 14A, FIG. 10A and FIG. 10B, two adjacentfirst touch sub-electrodes 111 included in the electrode portion 126 andtwo adjacent first touch sub-electrodes 111 included in the electrodeportion 127 are respectively, electrically connected with each other atleast via the corresponding connecting sub-electrodes 32.

The connecting mode of the first touch electrode 11 separated into twoelectrode portions (e.g., the electrode portion 112 and the electrodeportion 113) by the opening region 422 will be exemplarily illustratedbelow in connection with FIG. 14A, FIG. 20A and FIG. 20B.

FIG. 20A is a plane schematic diagram of a partial region REGL6 of thetouch sensor shown 01 in FIG. 14A; FIG. 20B is a sectional schematicdiagram along an line FF′ in FIG. 20A; and FIG. 20C is another sectionalschematic diagram along the line FF′ in FIG. 20A. For example, forexample, as shown in FIG. 14A and FIG. 20A, at least one of theplurality of first touch electrodes 11 is separated into two electrodeportions (e.g., the electrode portion 112 and the electrode portion 113)by the opening region 422; the touch sensor 01 further includes at leastone jumper conductor wire 21, and at least one jumper conductor wire 21at least partially surrounds (e.g., partially surrounds) the openingregion 422; and the electrode portion 112 and the electrode portion 113are electrically connected with each other via at least one jumperconductor wire 21 and a transition touch electrode 15.

For example, by arranging at least one first jumper conductor wire 21and the transition touch electrode 15, two electrode portions of thefirst touch electrode 11 that are separated by the opening region can beelectrically connected with each other, so that poor touch, caused bythe opening region, in a region where part of the first touch electrodes11 are positioned can be avoided.

For example, as shown in FIG. 14A and FIG. 20A, the transition touchelectrode 15 is at least partially positioned between the opening region422 and the opening region 421, and includes a transition touchsub-electrode 151 and a transition touch sub-electrode 152 arranged sideby side in the first direction D1 and electrically connected with eachother. For example, the transition touch electrode 15 further includes aconnecting sub-electrode 31 for electrically connecting the transitiontouch sub-electrode 151 and the transition touch sub-electrode 152.

For example, as shown in FIG. 14A and FIG. 20A, the transition touchsub-electrode 151 at least partially surrounds the opening region 422,and the transition touch sub-electrode 152 at least partially surrounds(e.g., fully surrounds) the opening region 421. For example, as shown inFIG. 14A, the transition touch sub-electrode 151 is arranged on one sideof the opening region 422 close to the opening region 421, and partiallysurrounds the opening region 422.

For example, as shown in FIG. 14A and FIG. 20A, the electrode portion112 and the transition touch sub-electrode 151 are electricallyconnected with each other at least via at least one jumper conductorwire 21 and the corresponding connecting sub-electrode 31; thetransition touch sub-electrode 151 and the transition touchsub-electrode 152 are electrically connected with each other via thecorresponding connecting sub-electrode 31; and the transition touchsub-electrode 152 and the electrode portion 113 are electricallyconnected with each other via the corresponding connecting sub-electrode31.

In some examples, the touch sensor 01 shown in FIG. 20A can furtherinclude a crack blocking ring 29 and a crack blocking ring 292 (which isnot shown in FIG. 20A) as shown in FIG. 36, and in such a case, thesectional schematic diagram along the line FF′ in FIG. 20A is as shownin FIG. 20B, and is not repeated herein for simplicity.

The electrical connecting mode of the electrode portion 112 and thetransition touch sub-electrode 151 will be exemplarily illustrated belowin connection with FIG. 14A, FIG. 20A and FIG. 20B.

For example, as shown in FIG. 20A and FIG. 20B, the touch sensor furtherincludes a first conducting electrode 211, and the first conductingelectrode 211 is directly connected with the end portion of the jumperconductor wire 21 close to the electrode portion 112. for example, thefirst conducting electrode 211 (e.g., a conducting block) and the jumperconductor wire 21 are made of the same material, positioned in the sameelectrode layer (e.g., the second electrode layer 30), and in contactwith the same film layer (e.g., the insulating layer 35); and forexample, the first conducting electrode 211 and the jumper conductorwire 21 are of an integrated structure. For example, the firstconducting electrode 211 and the jumper conductor wire 21 are of anintegrated structure, i.e., the first conducting electrode 211 and thejumper conductor wire 21 are formed in the same patterning process, andthere is no interface therebetween.

For example, as shown in FIG. 20A, one side (i.e., the side close to thejumper conductor wire 21) of two sides of the first conducting electrode211 opposite in the second direction D2 is directly connected with theend portion (i.e., the end portion close to the first conductingelectrode 211) of the jumper conductor wire 21 connected with the firstconducting electrode 211.

For example, a ratio of a side length of two sides of the firstconducting electrode 211 opposite in the first direction D1 to a linewidth of the jumper conductor wire 21 connected with the firstconducting electrode 211 is 16 to 400.

For example, as shown in FIG. 20A and FIG. 20B, the electrode portion112 and the first conducting electrode 211 are electrically connectedwith each other via the corresponding connecting sub-electrode 31 andring-shaped sub-electrode 134. It should be noted that in some examples,the ring-shaped sub-electrode 134 can also be used as one portion of theelectrode portion 112. Herein, for describing the transferring processof the signal more clearly, the ring-shaped sub-electrode 134 and theelectrode portion 112 are described as two parts, but the embodiments ofthe present disclosure are not limited thereto.

For example, as shown in FIG. 20A and FIG. 20B, the ring-shapedsub-electrode 134 and at least one first touch sub-electrode 111included in the electrode portion 112 are electrically connected via theconnecting sub-electrode 31 corresponding to at least one first touchsub-electrode 111 included in the electrode portion 112 and thering-shaped sub-electrode 134; and the ring-shaped sub-electrode 134 andthe corresponding first conducting electrode 211 are electricallyconnected via the corresponding connecting sub-electrode 31 (i.e., theconnecting sub-electrode 31 corresponding to the ring-shapedsub-electrode 134 and the corresponding first conducting electrode 211).

For example, as shown in FIG. 20A and FIG. 20B, the first conductingelectrode 211 and the corresponding connecting sub-electrode 31 arepositioned on different electrode layers and partially overlap; and inthe direction perpendicular to the touch sensor 01, there is theinsulating layer 35 between the first conducting electrode 211 and thecorresponding connecting sub-electrode 31, and the first conductingelectrode 211 and a first end of the corresponding connectingsub-electrode 31 are electrically connected with each other via the viahole in the insulating layer 35. For example, as shown in FIG. 20A, thefirst conducting electrode 211 is electrically connected with twoconnecting sub-electrodes 31 arranged side by side in the seconddirection D2.

For example, as shown in FIG. 20A and FIG. 20B, a second end of thecorresponding connecting sub-electrode 31 and the correspondingring-shaped sub-electrode 134 are electrically connected with each othervia the via hole in the insulating layer 35. For example, as shown inFIG. 20A and FIG. 20B, the ring-shaped sub-electrode 134 electricallyconnected with the first conducting electrode 211 is electricallyconnected with the electrode portion 112 (e.g., at least one first touchsub-electrode 111 included in the electrode portion 112) via thecorresponding connecting sub-electrode 31 and the via hole in theinsulating layer 35.

For example, as shown in FIG. 14A, FIG. 20A and FIG. 20B, a signal onthe electrode portion 112 (e.g., at least one first touch sub-electrode111 included in the electrode portion 112) can be transferred to thetransition touch sub-electrode 151 sequentially via the connectingsub-electrode 31, the ring-shaped sub-electrode 134, the connectingsub-electrode 31, the first conducting electrode 211 and the jumperconductor wire 21.

For example, as shown in FIG. 20A and FIG. 20B, the number of theconnecting sub-electrodes 31 (i.e., the connecting sub-electrodes 31 forelectrically connecting the ring-shaped sub-electrode 134 and thecorresponding first conducting electrode 211) corresponding to thering-shaped sub-electrode 134 and the corresponding first conductingelectrode 211 is greater than or equal to 2; the connectingsub-electrodes 31 corresponding to the ring-shaped sub-electrode 134 andthe corresponding first conducting electrode 211 are arranged side byside in the second direction D2; and a distance between two sides of twooutermost connecting sub-electrodes 31 away from each other in thesecond direction D2 in the connecting sub-electrodes 31 corresponding tothe ring-shaped sub-electrode 134 and the corresponding first conductingelectrode 211 is less than that between two sides of the correspondingfirst conducting electrode 211 opposite in the second direction D2.

For example, the distance (i.e., the width of the connectingsub-electrode 31 in the second direction D2) between two opposite sidesof at least one of the connecting sub-electrodes 31 corresponding to thering-shaped sub-electrode 134 and the corresponding first conductingelectrode 211 in the second direction D2 is 20 microns to 200 microns.For example, a distance between adjacent sides of two adjacentconnecting sub-electrodes 31 in the connecting sub-electrodes 31corresponding to the ring-shaped sub-electrode 134 and the correspondingfirst conducting electrode 211 in the second direction D2 is 5 micronsto 100 microns. For example, a distance between two sides of at leastone first conducting electrode 211 opposite in the first direction D1 is0.08 millimeter to 2.0 millimeters; and the distance between two sidesof at least one first conducting electrode 211 opposite in the seconddirection D2 is 0.08 millimeter to 2.0 millimeters.

For example, as shown in FIG. 20A and FIG. 20B, the jumper conductorwire 22 partially overlaps with the connecting sub-electrode 31 (i.e.,the connecting sub-electrodes 31 for electrically connecting thering-shaped sub-electrode 134 and the corresponding first conductingelectrode 211) corresponding to the ring-shaped sub-electrode 134 andthe corresponding first conducting electrode 211 in the directionperpendicular to the touch sensor 01.

For example, as shown in FIG. 20B, the first electrode layer 10 of thetouch sensor further includes a plurality of dummy electrodes 137 spacedfrom each other.

For example, as shown in FIG. 14A and FIG. 20A, the end portion of thejumper conductor wire 21 away from the electrode portion 112 is directlyconnected with the transition touch sub-electrode 151. For example, theend portion of the jumper conductor wire 21 away from the electrodeportion 112 is in direct contact with the transition touch sub-electrode151. For example, the end portion of the jumper conductor wire 21 awayfrom the electrode portion 112 and a first transition touchsub-electrode 151 are positioned on different electrode layers in thedirection perpendicular to the touch sensor 01; and the end portion ofthe jumper conductor wire 21 away from the electrode portion 112 is indirect contact with the surface of the first transition touchsub-electrode 151.

For example, as shown in FIG. 14A and FIG. 20A, compared to the jumperconductor wire 21, the jumper conductor wire 21 is farther away from theedge of the opening region 422, and in such a case, the jumper conductorwire 21 and the jumper conductor wire 22 can be positioned in the sameelectrode layer, and in contact with the same film layer (e.g., theinsulating layer 35) without causing a short circuit of the first touchelectrode 11 and the second touch electrode 12, and thus, the structureand the manufacturing process of the touch sensor 01 can be simplified.

For example, at least one jumper conductor wire 21 can be made of ametal material, and in such a case, the channel impedance (e.g.,resistance) between the electrode portion 112 and the transition touchsub-electrode 151 can be reduced, so that the electric signal can passthrough the at least one jumper conductor wire 21 more easily, and thus,touch performance can be improved.

In an example, as shown in FIG. 20B, the jumper conductor wire 21, thejumper conductor wire 22 and the first conducting electrode 211 arepositioned in the same electrode layer, so that the structure and themanufacturing process of the touch sensor 01 can be simplified, but theembodiments of the present disclosure are not limited thereto. Inanother example, the jumper conductor wire 21, the jumper conductor wire22 and the first conducting electrode 211 can also be respectivelypositioned on a plurality of electrode layers.

The electrical connecting mode of the transition touch sub-electrode 151and the transition touch sub-electrode 152 will be exemplarilyillustrated below in connection with FIG. 14A, FIG. 29A and FIG. 29B.

For example, as shown in FIG. 14A, FIG. 29A and FIG. 29B, the transitiontouch sub-electrode 151 and the transition touch sub-electrode 152 areelectrically connected via the corresponding connecting sub-electrode31; the transition touch sub-electrode 151 and the correspondingconnecting sub-electrode 31 are positioned on different electrode layersand partially overlap; and in the direction perpendicular to the touchsensor 01, there is the insulating layer 35 between the transition touchsub-electrode 151 and the corresponding connecting sub-electrode 31, andthe transition touch sub-electrode 151 and the first end of thecorresponding connecting sub-electrode 31 are electrically connectedwith each other via the via hole in the insulating layer 35. Forexample, as shown in FIG. 14A, FIG. 29A and FIG. 29B, the transitiontouch sub-electrode 152 and the corresponding connecting sub-electrode31 are positioned on different electrode layers and partially overlap;and in the direction perpendicular to the touch sensor 01, there is theinsulating layer 35 between the transition touch sub-electrode 152 andthe corresponding connecting sub-electrode 31, and the transition touchsub-electrode 152 and the second end of the corresponding connectingsub-electrode 31 are electrically connected with each other via the viahole in the insulating layer 35.

For example, as shown in FIG. 29B, the transition touch sub-electrode151 and the transition touch sub-electrode 152 are positioned in thesame electrode layer, and in contact with the same film layer (e.g., theinsulating layer 35), so that the structure and the manufacturingprocess of the touch sensor 01 can be simplified, but the embodiments ofthe present disclosure are not limited thereto, the transition touchsub-electrode 151 and the transition touch sub-electrode 152 can also berespectively positioned on different electrode layers. For example, boththe transition touch sub-electrode 151 and the transition touchsub-electrode 152 are positioned on the first electrode layer 10. Forexample, the transition touch sub-electrode 151 is positioned in thesame electrode layer with the transition touch sub-electrode 152, theplurality of first touch sub-electrodes 111, the plurality of secondtouch sub-electrodes 121, the plurality of ring-shaped sub-electrodes134 and the plurality of intermediate sub-electrodes 133.

For example, as shown in FIG. 14A, FIG. 29A and FIG. 29B, a signal onthe transition touch sub-electrode 151 can be transferred to thetransition touch sub-electrode 152 via the connecting sub-electrode 31.

For example, as shown in FIG. 14A, FIG. 29A and FIG. 29B, a dummyelectrode 135 is arranged between the transition touch sub-electrode 151and the transition touch electrode 16, and a dummy electrode 136 isarranged between the transition touch sub-electrode 152 and thetransition touch electrode 16, i.e., the touch sensor further includesthe dummy electrode 135 and the dummy electrode 136. For example, byarranging the dummy electrode 135 and the dummy electrode 136, adistance between the transition touch sub-electrode 151 and thetransition touch electrode 16 and a distance between the transitiontouch sub-electrode 152 and the transition touch electrode 16 can becontrolled better, so that a signal-to-noise ratio of a touch sensingsignal provided by the transition touch electrode 15 and the transitiontouch electrode 16 can be controlled better.

For example, as shown in FIG. 29, the dummy electrode 135 includes aplurality of bent structures 1351, and a plurality of first protrudingportions 161 are arranged in the corresponding bent structures 1351; andthe dummy electrode 136 includes a plurality of bent structures 1361,and a plurality of second protruding portions 162 are arranged in thecorresponding bent structures 1361.

The electrical connecting mode of the transition touch sub-electrode 152and the electrode portion 113 will be exemplarily illustrated below inconnection with FIG. 14A, FIG. 26A and FIG. 26B.

For example, as shown in FIG. 14A, the transition touch sub-electrode152 fully surrounds the opening region 421. for example, by enabling thetransition touch sub-electrode 152 to fully surround the opening region421, the transition touch sub-electrode 152 and the electrode portion113 can be electrically connected with each other in the case of notadditionally arranging the jumper conductor wire between the transitiontouch sub-electrode 152 and the electrode portion 113.

For example, as shown in FIG. 14A, FIG. 26A and FIG. 26B, the electrodeportion 113 (i.e., the first touch sub-electrode 111 which is includedin the electrode portion 113 and is the closest to the electrode portion112) and the transition touch sub-electrode 152 are electricallyconnected with each other via the corresponding connecting sub-electrode31 (e.g., two connecting sub-electrodes 31 arranged side by side in thesecond direction D2).

For example, as shown in FIG. 14A, FIG. 26A and FIG. 26B, the transitiontouch sub-electrode 152 and the corresponding connecting sub-electrode31 are positioned on different electrode layers and partially overlap;and in the direction perpendicular to the touch sensor 01, there is theinsulating layer 35 between the transition touch sub-electrode 152 andthe above-mentioned corresponding connecting sub-electrode 31, and thetransition touch sub-electrode 152 and the first end of theabove-mentioned corresponding connecting sub-electrode 31 areelectrically connected with each other via the via hole in theinsulating layer 35. For example, as shown in FIG. 14A, FIG. 26A andFIG. 26B, the electrode portion 113 (e.g., the first touch sub-electrode111 which is included in the electrode portion 113 and is the closest tothe electrode portion 112) and the above-mentioned correspondingconnecting sub-electrode 31 are positioned on different electrode layersand partially overlap; and in the direction perpendicular to the touchsensor 01, there is the insulating layer 35 between the electrodeportion 113 (e.g., the first touch sub-electrode 111 which is includedin the electrode portion 113 and is the closest to the electrode portion112) and the above-mentioned corresponding connecting sub-electrode 31,and the electrode portion 113 (e.g., the first touch sub-electrode 111which is included in the electrode portion 113 and is the closest to theelectrode portion 112) and the second end of the above-mentionedcorresponding connecting sub-electrode 31 are electrically connectedwith each other via the via hole in the insulating layer 35.

For example, as shown in FIG. 14A, FIG. 26A and FIG. 26B, a signal onthe transition touch sub-electrode 152 can be transferred to theelectrode portion 113 via the connecting sub-electrode 31.

For example, as shown in FIG. 14A, FIG. 20A, FIG. 20B, FIG. 26A, FIG.26B, FIG. 29A and FIG. 29B, the signal on the electrode portion 112(e.g., the first touch sub-electrode 111 which is included in theelectrode portion 112 and is the closest to the electrode portion 113)can be transferred to the electrode portion 113 (e.g., the first touchsub-electrode 111 which is included in the electrode portion 113 and isthe closest to the electrode portion 112) sequentially via theconnecting sub-electrode 31, the ring-shaped sub-electrode 134, theconnecting sub-electrode 31, the first conducting electrode 211, thejumper conductor wire 21, the transition touch sub-electrode 151, theconnecting sub-electrode 31, the transition touch sub-electrode 152 andthe connecting sub-electrode 31.

It should be noted that the disclosure is not limited to the case thatthe electrode portion 112 and the electrode portion 113 are electricallyconnected with each other via the jumper conductor wire 21, thetransition touch electrode 15 and the corresponding connectingsub-electrode 31, and in some examples (e.g., the touch sensor onlyincludes the opening region 422, but does not include the opening region421, or the transition touch electrode 15 is not arranged between theopening region 422 and the opening region 421), the electrode portion112 and the electrode portion 113 can be electrically connected witheach other via the jumper conductor wire 21 and the correspondingconnecting sub-electrode 31 instead of the transition touch electrode15.

For example, as shown in FIG. 14A, FIG. 10A and FIG. 10B, two adjacentfirst touch sub-electrodes 111 included in the electrode portion 112 andtwo adjacent first touch sub-electrodes 111 included in the electrodeportion 113 are respectively, electrically connected with each other viathe corresponding connecting sub-electrodes 31 and ring-shapedsub-electrodes 133.

Although the touch sensor 01 of the display apparatus 03 shown in FIG.14A to FIG. 19, FIG. 20A, FIG. 20B and other related drawings issimultaneously provided with the jumper conductor wire 21 and the jumperconductor wire 22, the embodiments of the present disclosure are notlimited thereto. For example, according to practical applicationdemands, the touch sensor 01 of the display apparatus 03 shown in FIG.14A to FIG. 19, FIG. 20A, FIG. 20B and other related drawings can alsobe only provided with any one of the jumper conductor wire 21 and thejumper conductor wire 22; and in such a case, two portions of the firsttouch electrode 11 disconnected by the opening region can beelectrically connected, or two portions of the second touch electrode 12disconnected by the opening region can be electrically connected.

In some examples, as shown in FIG. 8 and FIG. 9, the touch sensorincludes the opening region 422, the opening region 421, a plurality offirst touch electrodes 11 and a plurality of second touch electrodes 12.The opening region 422 and the opening region 421 are spaced; the center013 of the opening region 422 and the center 011 of the touch sensor donot coincide, and the center 012 of the opening region 421 and thecenter 011 of the touch sensor do not coincide; the plurality of firsttouch electrodes 11 respectively extend along the first direction D1,and at least one of the plurality of first touch electrodes 11 includesa plurality of first touch sub-electrodes 111 arranged side by side inthe first direction D1 and electrically connected with each other; theplurality of second touch electrodes 12 respectively extend along thesecond direction D2 intersecting with the first direction D1, and atleast one of the plurality of second touch electrodes 12 includes aplurality of second touch sub-electrodes 121 arranged side by side inthe second direction D2 and electrically connected with each other; theplurality of first touch electrodes 11 are arranged side by side alongthe second direction D2, and the plurality of second touch electrodes 12are arranged side by side along the first direction D1; the plurality offirst touch sub-electrodes 111 and the plurality of second touchsub-electrodes 121 together at least partially surround the openingregion 421 and the opening region 421; at least one of the plurality offirst touch electrodes 11 includes a transition touch electrode 15; eachof one group of second touch electrodes 12 in the plurality of secondtouch electrodes 12 includes the transition touch electrode 16; thetransition touch electrode 15 is at least partially positioned betweenthe opening region 422 and the opening region 421, and includes thetransition touch sub-electrode 151 and the transition touchsub-electrode 152 arranged side by side in the first direction D1 andelectrically connected with each other; the transition touchsub-electrode 151 at least partially surrounds the opening region 422,and the transition touch sub-electrode 152 at least partially surroundsthe opening region 421; and the transition touch electrode 16 is atleast partially positioned between the transition touch sub-electrode151 and the transition touch sub-electrode 152, and extends along thesecond direction D2.

For example, by arranging the transition touch electrode 15 and thetransition touch electrode 16 between the opening region 422 and theopening region 421, the touch sensor 01 can identify a touch operationexecuted in a region of the touch sensor 01 positioned between theopening region 422 and the opening region 421, so that the userexperience is improved. The structures of the transition touch electrode15 and the transition touch electrode 16 will be exemplarily illustratedbelow in connection with FIG. 21 to FIG. 23.

FIG. 21 is a plane schematic diagram of a partial region REG 5 of thetouch sensor shown in FIG. 8. For example, as shown in FIG. 21, a firstedge of the opening region 422 facing the opening region 421 is of afirst shape, and an edge of the transition touch sub-electrode 151facing the first edge integrally is also of the first shape; and asecond edge of the opening region 421 facing the opening region 422 isof a second shape, and an edge of the transition touch sub-electrode 152facing the second edge integrally is also of the second shape. Forexample, as shown in FIG. 21, the first shape is different from thesecond shape, but the embodiments of the present disclosure are notlimited thereto, and in some examples, the first shape is the same withthe second shape.

For example, as shown in FIG. 21, the opening region 422 is of aracetrack shape, and the opening region 421 is of a circle shape; andcorrespondingly, the first shape is a portion of the racetrack shape,and the second shape is a portion of the circle shape. It should benoted that the shape of the opening region 422 and the shape of theopening region 421 are not limited to the racetrack shape and the circleshape respectively, and according to practical application demands, theshape of the opening region 422 and the shape of the opening region 421may be both of the racetrack shape, the circle shape or other applicableshapes.

For example, as shown in FIG. 21, an edge of the transition touchelectrode 16 close to the transition touch sub-electrode 151 includes aplurality of first protruding portions 161 protruding towards thetransition touch sub-electrode 151; an edge of the transition touchelectrode 16 close to the transition touch sub-electrode 152 includes aplurality of second protruding portions 162 protruding towards thetransition touch sub-electrode 152; an edge of the transition touchsub-electrode 151 close to the transition touch electrode 16 includes aplurality of first sunk portions 1511; an edge of the transition touchsub-electrode 152 close to the transition touch electrode 16 includes aplurality of second sunk portions 1521; the plurality of firstprotruding portions 161 are correspondingly arranged in the plurality offirst sunk portions 1511; the plurality of second protruding portions162 are correspondingly arranged in the plurality of second sunkportions 1521; and in such a case, the plurality of first protrudingportions 161 included in the edge of the transition touch electrode 16close to the transition touch sub-electrode 151 are surrounded by thetransition touch sub-electrode 151, and the plurality of secondprotruding portions 162 included in the edge of the transition touchelectrode 16 close to the transition touch sub-electrode 152 aresurrounded by the transition touch sub-electrode 152.

For example, by correspondingly arranging the plurality of firstprotruding portions 161 in the plurality of first sunk portions 1511, aregion between the shape of the opening region 422 and the openingregion 421 can be more effectively utilized and a mutual capacitancebetween the transition touch electrode 16 and the transition touchsub-electrode 151 can be increased, and by correspondingly arranging theplurality of second protruding portions 162 in the plurality of secondsunk portions 1521, the region between the shape of the opening region422 and the opening region 421 can be more effectively utilized and themutual capacitance between the transition touch electrode 16 and thetransition touch sub-electrode 151 can be increased; and in such a case,a signal-to-noise ratio of a touch sensing signal provided by a portionof the touch sensor 01 positioned between the opening region 422 and theopening region 421 can be increased, and touch performance of theportion of the touch sensor 01 positioned between the opening region 422and the opening region 421 can be improved.

For example, as shown in FIG. 21, the plurality of first protrudingportions 161 are sequentially arranged in the second direction D2; theplurality of second protruding portions 162 are sequentially arranged inthe second direction D2; the edge of the transition touch electrode 16close to the transition touch sub-electrode 151 further includes aplurality of third sunk portions 163; and the edge of the transitiontouch electrode 16 close to the transition touch sub-electrode 152further includes a plurality of fourth sunk portions 164. For example,as shown in FIG. 21, the plurality of third sunk portions 163 and theplurality of fourth sunk portions 164 correspond one to one. Forexample, as shown in FIG. 21, the bottom of each of the plurality ofthird sunk portions 163 overlap with the bottom of the fourth sunkportion 164 corresponding to each of the plurality of third sunkportions 163 in the first direction D1.

For example, as shown in FIG. 21, there is one third sunk portion 163between two adjacent (e.g., any two adjacent) first protruding portions161, and there is one fourth sunk portion 164 between two adjacent(e.g., any two adjacent) second protruding portions 162.

For example, as shown in FIG. 21, a distance between the bottom of thethird sunk portion 163 and the bottom of the fourth sunk portion 164 inthe first direction D1 is less than a size of any one of the pluralityof first protruding portions 161 and the plurality of second protrudingportions 162 in the first direction D1; and in such a case, the sizes ofthe first protruding portion 161 and the second protruding portion 162in the first direction D1 can be increased in the case that an area ofthe region between the opening region 422 and the opening region 421 isfixed, so that the mutual capacitance between the transition touchelectrode 16 and the transition touch sub-electrode 151 and the mutualcapacitance between the transition touch electrode 16 and the transitiontouch sub-electrode 152 can be increased, the signal-to-noise ratio ofthe touch sensing signal provided by the portion of the touch sensor 01positioned between the opening region 422 and the opening region 421 canbe further increased, and touch performance (e.g., the touchsensitivity) of the portion of the touch sensor 01 positioned betweenthe opening region 422 and the opening region 421 can be improved.

For example, the plurality of first protruding portions 161 and theplurality of second protruding portions 162 correspond one to one; and adistance between a vertex of each of the plurality of first protrudingportions 161 and a vertex of the corresponding second protruding portion162 in the first direction D1 is less than a minimum distance betweenthe edge of the opening region 422 and the edge of the opening region421 in the first direction D1.

For example, the minimum distance between the edge of the opening region422 and the edge of the opening region 421 in the first direction D1refers to the distance between a point, the closest to the openingregion 421, at the edge of the opening region 422 and a point, theclosest to the opening region 422, at the edge of the opening region 421in the first direction D1.

It should be noted that the distance between the two points in the firstdirection D1 refers to the distance between virtual straight lines whichrespectively pass through the two points and are perpendicular to thefirst direction D1.

For example, the distance between the vertex of each of the plurality offirst protruding portions 161 and the vertex of the corresponding secondprotruding portion 162 in the first direction D1 refers to the distancebetween a virtual straight line which passes through the vertex of eachof the plurality of first protruding portions 161 and is perpendicularto the first direction D1 and a virtual straight line which passesthrough the vertex of the corresponding second protruding portion 162and is perpendicular to the first direction D1.

For example, the distance between the vertex of each of the plurality offirst protruding portions 161 and the vertex of the corresponding secondprotruding portion 162 in the first direction D1 is less than a distancebetween two points of at least one of a plurality of first touchsub-electrodes 111 in the first direction D1 that are farthest away fromeach other in the first direction D1 or a distance between two points ofat least one of a plurality of second touch sub-electrodes 121 in thefirst direction D1 that are farthest away from each other in the firstdirection D1.

For example, the size of any one of the plurality of first protrudingportions 161 and the plurality of second protruding portions 162 in thefirst direction D1 is greater than three times of the distance betweenthe bottom of the corresponding third sunk portion 163 and the bottom ofthe corresponding fourth sunk portion 164 in the first direction D1.

For example, FIG. 22A shows an enlarged diagram of the transition touchelectrode 16 of the touch sensor 01 shown in FIG. 21. As shown in FIG.22A, the bottoms of the plurality of third sunk portions 163 are allpositioned on a first virtual straight line 1631 in parallel with thesecond direction D1, the bottoms of the plurality of fourth sunkportions 164 are all positioned on a second virtual straight line 1641in parallel with the second direction D1, and the first virtual straightline 1631 is in parallel with the second virtual straight line 1641; andin such a case, the distance d_c between the bottom of the third sunkportion 163 and the bottom of the fourth sunk portion 164 in the firstdirection D1 refers to the distance between the first virtual straightline 1631 and the second virtual straight line 1641 in the firstdirection D1, a size s1 of the first protruding portion 161 in the firstdirection D1 refers to the distance between the top of the firstprotruding portion 161 and the first virtual straight line 1631 (or thebottom of the first protruding portion 161) in the first direction D1,and a size s2 of the second protruding portion 162 in the firstdirection D1 refers to the distance between the top of the secondprotruding portion 162 and the second virtual straight line 1641 (or thebottom of the second protruding portion 162) in the first direction D1.

For example, the plurality of first protruding portions 161 are the samein size, and the plurality of second protruding portions 162 are thesame in size. For example, the size of the plurality of first protrudingportions 161 and the size of the plurality of second protruding portions162 are the same (e.g., are both a first size). For example, the firstsize is 3 to 12 (e.g., 5, 8 or 10) times of the distance d_c between thebottom of the third sunk portion 163 and the bottom of the fourth sunkportion 164 in the first direction D1.

For example, as shown in FIG. 21 and FIG. 22A, the transition touchsub-electrode 151 and the transition touch sub-electrode 152 areelectrically connected with each other via the corresponding connectingsub-electrode 31 (refer to FIG. 29B below). For example, as shown inFIG. 21 and FIG. 22A, the connecting sub-electrode 31 for electricallyconnecting the transition touch sub-electrode 151 and the transitiontouch sub-electrode 152 overlaps with the bottom of the correspondingthird sunk portion 163 and the bottom of the corresponding fourth sunkportion 164, and in such a case, a size of the connecting sub-electrode31 in the first direction D1 can be shortened, so that influence of theconnecting sub-electrode 31 on display quality of the display apparatus03 can be reduced.

For example, as shown in FIG. 21, the transition touch sub-electrode 151and the transition touch sub-electrode 152 are electrically connectedwith each other via a plurality of connecting sub-electrodes 31 arrangedside by side in the second direction D2. For example, as shown in FIG.21, the transition touch electrode 16 includes a plurality of transitiontouch sub-electrodes 165 arranged side by side in the second directionD2 and electrically connected with each other. For example, theplurality of transition touch sub-electrodes 165 are of an integratedstructure, i.e., the plurality of transition touch sub-electrodes 165are formed from the same material in the same patterning process, andthere is no interface between the adjacent transition touchsub-electrodes 165.

For example, as shown in FIG. 21, two transition touch sub-electrodes165 are respectively arranged on both sides of each of the plurality ofconnecting sub-electrodes 31 for electrically connecting the transitiontouch sub-electrode 151 and the transition touch sub-electrode 152. Forexample, as shown in FIG. 21, each of the plurality of transition touchsub-electrodes 165 includes at least one first protruding portion 161and at least one second protruding portion 162; the at least one firstprotruding portion 161 and the at least one second protruding portion162 correspond one to one; and any two adjacent transition touchsub-electrodes 165 are directly connected.

It should be noted that the disclosure is not limited to the case thatthe transition touch sub-electrode 151 and the transition touchsub-electrode 152 are electrically connected with each other via threeconnecting sub-electrodes 31; for example, the number of the connectingsub-electrodes 31 for electrically connecting the transition touchsub-electrode 151 and the transition touch sub-electrode 152 is greaterthan or equal to 1 and less than or equal to the number of the pluralityof fourth sunk portions 164; and for another example, according topractical application demands, the transition touch sub-electrode 151and the transition touch sub-electrode 152 can be electrically connectedwith each other via one, five or other applicable numbers of connectingsub-electrodes 31.

For example, the distance from the vertex of any one of the plurality offirst protruding portions 161 and the plurality of second protrudingportions 162 to the bottom of any one of the plurality of firstprotruding portions 161 and the plurality of second protruding portions162 (i.e., the size of any one of the plurality of first protrudingportions 161 and the plurality of second protruding portions 162 in thefirst direction D1) is greater than three times of the distance betweenthe bottom of the third sunk portion 163 and the bottom of thecorresponding fourth sunk portion 164 in the first direction D1.

For example, the bottom of the first protruding portion 161 refers to avirtual connecting line (e.g., the first virtual straight line 1631) ofthe bottoms of two third sunk portions 163 positioned on both sides ofthe first protruding portion 161 in the second direction D2. Forexample, the bottom of the second protruding portion 162 refers to avirtual connecting line (e.g., the second virtual straight line 1641) ofthe bottoms of two four sunk portions 164 positioned on both sides ofthe second protruding portion 162 in the second direction D2.

For example, the distance from the vertex of at least one of theplurality of first protruding portions 161 to the bottom of at least oneof the plurality of first protruding portions 161 is 0.5 millimeter to1.0 millimeter, and the distance from the vertex of at least one of theplurality of second protruding portions 162 to the bottom of at leastone of the plurality of second protruding portions 162 is 0.5 millimeterto 1.0 millimeter.

For example, the distance (the distance between extending directionsperpendicular to the edge of the transition touch sub-electrode 151)between the edge of the transition touch sub-electrode 151 close to thetransition touch electrode 16 and the edge of the transition touchelectrode 16 close to the transition touch sub-electrode 151 is 40microns to 90 microns.

For example, the number of the plurality of first protruding portions161 is 3 to 12, and the number of the plurality of second protrudingportions is 3 to 12.

FIG. 22B shows another enlarged diagram of the transition touchelectrode of the touch sensor shown in FIG. 21. For example, as shown inFIG. 22B, an inclination angle α1 of side edges (or side surfaces) ofthe plurality of first protruding portions 161 with respect to thesecond direction D2 is 30° to 85°, and an inclination angle α2 of sideedges (or side surfaces) of the plurality of second protruding portions162 with respect to the second direction D2 is 30° to 85°. For example,the side surfaces of the plurality of first protruding portions 161 andthe plurality of second protruding portions 162 include circular conicalsurfaces, but the embodiments of the present disclosure are not limitedthereto.

For example, the ratio of the distance between the center 013 of theopening region 422 and the center 012 of the opening region 421 in thefirst direction D1 to the distance between two points of the first touchsub-electrode 111 with the maximum area in the plurality of first touchsub-electrodes 111 (or the second touch sub-electrode 121 with themaximum area in the plurality of second touch sub-electrodes 121) in thefirst direction D1 that are farthest away from each other in the firstdirection D1 is 2 to 3.

FIG. 23 is a plane schematic diagram of a partial region REG5 of thetouch sensor 01 shown in FIG. 9. For example, as shown in FIG. 23, thetransition touch sub-electrode 152 fully surrounds the opening region421; the transition touch sub-electrode 152 has an inner edge 1522 andan outer edge 1523; and the inner edge 1522 of the transition touchsub-electrode 152 fully surrounds the opening region 421.

For example, as shown in FIG. 23, the inner edge 1522 of the transitiontouch sub-electrode 152 is the same in shape with the opening region421. For example, both the inner edge 1522 of the transition touchsub-electrode 152 and the opening region 421 are of a circle shape.

For example, by enabling the transition touch sub-electrode 152 to fullysurround the opening region 421, an area (e.g., an active electrodearea) of the transition touch sub-electrode 152 can be increased, sothat the amount of signals and touch performance of the touch sensor 01can be improved.

For example, the transition touch sub-electrode 151, the transitiontouch sub-electrode 152 and the transition touch electrode 16 may bepositioned in the same electrode layer (e.g., the first electrode layer10), and in contact with the same film layer (e.g., the insulating layer35), so that the structure and the manufacturing process of the touchsensor 01 can be simplified, but the embodiments of the presentdisclosure are not limited thereto, and for example, the transitiontouch sub-electrode 151, the transition touch sub-electrode 152 and thetransition touch electrode 16 may also be positioned on more than twoelectrode layers.

In an example, the transition touch sub-electrode 151, the transitiontouch sub-electrode 152, the transition touch electrode 16, theplurality of first touch sub-electrodes 111, the plurality of secondtouch sub-electrodes 121, the plurality of ring-shaped sub-electrodes134 and the plurality of intermediate sub-electrodes 133 are all made ofa transparent conducting material; and in such a case, the transitiontouch sub-electrode 151, the transition touch sub-electrode 152, thetransition touch electrode 16, the plurality of first touchsub-electrodes 111, the plurality of second touch sub-electrodes 121,the plurality of ring-shaped sub-electrodes 134 and the plurality ofintermediate sub-electrodes 133 can be prepared by the same process(e.g., the patterning process), and in contact with the same surface ofthe same film layer (e.g., all in contact with the surface of the basematerial 36 close to the first electrode layer 10).

In another example, a region where the transition touch sub-electrode151, the transition touch sub-electrode 152 and the transition touchelectrode 16 are positioned is the region between the shape of theopening region 422 and the opening region 421, and a region of thedisplay apparatus corresponding to the region between the shape of theopening region 422 and the opening region 421 is not used for display,and thus, the transition touch sub-electrode 151, the transition touchsub-electrode 152 and the transition touch electrode 16 can be made of ametal material; the plurality of first touch sub-electrodes 111, theplurality of second touch sub-electrodes 121, the plurality ofring-shaped sub-electrodes 134 and the plurality of intermediatesub-electrodes 133 are made of a transparent conducting material; and insuch a case, a patterning process for forming the transition touchsub-electrode 151, the transition touch sub-electrode 152 and thetransition touch electrode 16 and a patterning process for forming theplurality of first touch sub-electrodes 111, the plurality of secondtouch sub-electrodes 121, the plurality of ring-shaped sub-electrodes134 and the plurality of intermediate sub-electrodes 133 are completedat different moments.

For example, the electrode layer where the transition touchsub-electrode 151, the transition touch sub-electrode 152 and thetransition touch electrode 16 are positioned overlaps with the electrodelayer where the plurality of first touch sub-electrodes 111, theplurality of second touch sub-electrodes 121, the plurality ofring-shaped sub-electrodes 134 and the plurality of intermediatesub-electrodes 133 are positioned in the direction perpendicular to thetouch sensor 01. For another example, the electrode layer where thetransition touch sub-electrode 151, the transition touch sub-electrode152 and the transition touch electrode 16 are positioned and theelectrode layer where the plurality of first touch sub-electrodes 111,the plurality of second touch sub-electrodes 121, the plurality ofring-shaped sub-electrodes 134 and the plurality of intermediatesub-electrodes 133 are positioned are the same electrode layer, i.e.,the transition touch sub-electrode 151, the transition touchsub-electrode 152, the transition touch electrode 16, the plurality offirst touch sub-electrodes 111, the plurality of second touchsub-electrodes 121, the plurality of ring-shaped sub-electrodes 134 andthe plurality of intermediate sub-electrodes 133 are in contact with thesame surface of the same film layer (e.g., all in contact with thesurface of the base material 36 close to the first electrode layer 10),but a material for manufacturing the transition touch sub-electrode 151,the transition touch sub-electrode 152 and the transition touchelectrode 16 is different from a material for manufacturing theplurality of first touch sub-electrodes 111, the plurality of secondtouch sub-electrodes 121, the plurality of ring-shaped sub-electrodes134 and the plurality of intermediate sub-electrodes 133.

In some examples, the touch sensor 01 includes the opening region 421, aplurality of first touch electrodes 11, a plurality of second touchelectrodes 12 and a conducting structure 23. The center of the openingregion 421 and the center of the touch sensor 01 do not coincide; theplurality of first touch electrodes 11 respectively extend along thefirst direction D1, and at least one of the plurality of first touchelectrodes 11 includes a plurality of first touch sub-electrodes 111arranged side by side in the first direction D1 and electricallyconnected with each other; the plurality of second touch electrodes 12respectively extend along the second direction D2 intersecting with thefirst direction D1, and at least one of the plurality of second touchelectrodes 12 includes a plurality of second touch sub-electrodes 121arranged side by side in the second direction D2 and electricallyconnected with each other; the plurality of first touch electrodes 11are arranged side by side along the second direction D2, and theplurality of second touch electrodes 12 are arranged side by side alongthe first direction D1; the plurality of first touch sub-electrodes 111and the plurality of second touch sub-electrodes 121 together at leastpartially surround the opening region 422; each of one group of secondtouch electrodes 12 in the plurality of second touch electrodes 12further includes the transition touch electrode 14; the transition touchelectrode 14 extends in the second direction D2, and partially surroundsthe opening region 421 along the second direction D2; a virtual straightline 1451 passing through the center of the opening region 421 andextending along the first direction D1 respectively intersects with twosides of the transition touch electrode 14 at a first position 1452 anda second position 1453 opposite in the first direction D1, and adistance between the first position 1452 and the second position 1453 isless than the maximum width of at least one of the plurality of secondtouch sub-electrodes 121 in the first direction D1; and the conductingstructure 23 is positioned on the surface of the transition touchelectrode 14, at least partially surrounds the edge of the openingregion 421, and is electrically connected with the transition touchelectrode 14.

For example, by arranging a first conducting structure 23 on the surfaceof the transition touch electrode 14 and enabling the first conductingstructure 23 to be electrically connected (e.g., connected in parallelin the second direction D2) with the transition touch electrode 14, thechannel impedance of a region where the transition touch electrode 14 ispositioned (e.g., the resistance of the region where the transitiontouch electrode 14 is positioned) can be reduced, and the reliability(e.g., possibility of reducing an open circuit) of the region where thetransition touch electrode 14 is positioned can be promoted. Forexample, by reducing the channel impedance of the transition touchelectrode 14, the charge conductivity of the transition touch electrode14 can be improved, so that the electric signal (charges) passes throughthe transition touch electrode 14 more easily, and thus, touchperformance of a region of the touch sensor 01 corresponding to thetransition touch electrode 14 can be improved, and the possibility ofpoor touch, caused by electrostatic discharge (ESD) and electrostaticbreakdown, in the region where the transition touch electrode 14 ispositioned can be reduced.

Exemplary illustration will be carried out below in connection with FIG.24 to FIG. 28, FIG. 29A and FIG. 29B.

FIG. 24 is one more schematic diagram of the partial region REG1included in the touch sensor 01 of the display apparatus 03 shown inFIG. 4; FIG. 25 is a plane schematic diagram of the transition touchelectrode 14 shown in FIG. 24; FIG. 26A is a plane schematic diagram ofa partial region REGE1 shown in FIG. 24; and FIG. 26B is a sectionalschematic diagram along a line GG′ shown in FIG. 26A. FIG. 27 is a planeschematic diagram of a partial region REGE3 shown in FIG. 24.

For example, as shown in FIG. 24 to FIG. 26A, the touch sensor 01 (e.g.,at least one of the plurality of second touch electrodes 12 included inthe touch sensor 01) includes the transition touch electrode 14, whichat least partially surrounds the edge of the opening region 421 andpartially surrounds the opening region 421 along the second directionD2. For example, the transition touch electrode 14 and the edge of theopening region 421 partially overlap in the second direction D2.

For example, the transition touch electrode 14 extends in the seconddirection D2. For example, extension of the transition touch electrode14 in the second direction D2 does not represent that the transitiontouch electrode 14 is in parallel with the second direction D2, butrefers to such a case that a length of the transition touch electrode 14in the second direction D2 is greater than a width of the transitiontouch electrode 14 in the first direction D1.

For example, as shown in FIG. 24 to FIG. 26A, the virtual straight line1451 passing through the center of the opening region 421 and extendingalong the first direction D1 respectively intersects with two sides ofthe transition touch electrode 14 at the first position 1452 and thesecond position 1453 opposite to each other in the first direction D1,and the distance between the first position 1452 and the second position1453 is less than the maximum width of at least one of the plurality ofsecond touch sub-electrodes 121 (e.g., each of the plurality of secondtouch sub-electrodes 121) in the first direction D1.

For example, the maximum width of at least one of the plurality ofsecond touch sub-electrodes 121 in the first direction D1 refers to thedistance between two points of at least one of the plurality of secondtouch sub-electrodes 121 in the first direction D1 that are farthestaway from each other in the first direction D1. It should be noted thatthe distance between the two points in the first direction D1 refers tothe distance between the virtual straight lines which respectively passthrough the two points and are perpendicular to the first direction D1.

For example, the distance between the first position 1452 and the secondposition 1453 is relatively small, and the width of the transition touchelectrode 14 in the first direction D1 is relatively small, and thus, inthe case of not arranging the conducting structure 23, the channelimpedance of a portion of the touch sensor 01 is relatively highcorresponding to the transition touch electrode 14 (compared to thechannel impedance of the second touch sub-electrode 121).

For example, the resistance of the transition touch electrode 14 ishigher than that of at least one of the plurality of second touchsub-electrodes 121 (e.g., each of the plurality of second touchsub-electrodes 121).

For example, the maximum length of the transition touch electrode 14 inthe second direction D2 is greater than that of at least one of theplurality of second touch sub-electrodes 121 (e.g., each of theplurality of second touch sub-electrodes 121) in the second directionD2, so that the resistance of the transition touch electrode 14 isfurther improved.

For example, as shown in FIG. 25, the maximum length of the transitiontouch electrode 14 in the second direction D2 refers to the distancebetween two points (e.g., a point 1461 and a point 1462) of thetransition touch electrode 14 in the second direction D2 that arefarthest away from each other in the second direction D2.

It should be noted that the distance between the two points (e.g., thepoint 1461 and the point 1462) in the second direction D2 refers to thedistance between virtual straight lines (e.g., a virtual straight line1463 and a virtual straight line 1464) which respectively pass throughthe two points (e.g., the point 1461 and the point 1462) and areperpendicular to the second direction D2.

For example, the maximum length of at least one of the plurality ofsecond touch sub-electrodes 121 in the second direction D2 refers to thedistance between two points of at least one of the second touchsub-electrodes 121 in the second direction D2 that are farthest awayfrom each other in the second direction D2.

For example, as shown in FIG. 24 to FIG. 26A, the transition touchelectrode 14 includes a transition touch sub-electrode 141 and atransition touch sub-electrode 142. For example, as shown in FIG. 24 toFIG. 26A, the transition touch sub-electrode 141 and the transitiontouch sub-electrode 142 are arranged side by side in the seconddirection D2. For example, as shown in FIG. 24 to FIG. 26A, thetransition touch sub-electrode 141 and the transition touchsub-electrode 142 are directly connected. For example, the transitiontouch sub-electrode 141 and the transition touch sub-electrode 142 areof an integrated structure, i.e., the transition touch sub-electrode 141and the transition touch sub-electrode 142 are formed from the samematerial in the same patterning process, and there is no interfacebetween the transition touch sub-electrode 141 and the transition touchsub-electrode 142.

For example, as shown in FIG. 24 to FIG. 26A, the opening region 421includes an arc edge portion adjacent to the transition touch electrode14; and an overall outline of one side of the transition touch electrode14 close to the opening region 421 is an arc edge portion in parallelwith the arc edge portion of the opening region 421. For example, theoverall outline of one side of the transition touch electrode 14 closeto the opening region 421 being the arc edge portion in parallel withthe arc edge portion of the opening region 421 refer to a case that: theoverall outline (e.g., a smoothed outline) of one side of the transitiontouch electrode 14 close to the opening region 421 is of an arc shape,and the arc shape has the same shape and the same extending trend withthe arc edge portion of the opening region 421.

For example, as shown in FIG. 24, FIG. 26A and FIG. 26B, the firstconducting structure 23 is arranged on the surface of the transitiontouch electrode 14. For example, as shown in FIG. 26B, the firstconducting structure 23 is in direct contact with the transition touchelectrode 14, i.e., the first conducting structure 23 is electricallyconnected with the transition touch electrode 14. For example, as shownin FIG. 24, FIG. 26A and FIG. 26B, the first conducting structure 23 iselectrically connected (e.g., connected in parallel in the seconddirection D2) with the transition touch electrode 14.

For example, by arranging the first conducting structure 23 on thesurface of the transition touch electrode 14 and enabling the firstconducting structure 23 to be electrically connected (e.g., connected inparallel in the second direction D2) with the transition touch electrode14, the channel impedance of the region where the transition touchelectrode 14 is positioned can be reduced (e.g., the resistance of theregion where the transition touch electrode 14 is positioned can bereduced), and the charge conductivity of the region where the transitiontouch electrode 14 is positioned can be improved. In such case, thechannel impedance of the far end (i.e., one end away from a touchcircuit or a touch chip) of the second touch electrode 12 including thetransition touch electrode 14 is relatively low.

For example, a square resistance of the first conducting structure 23 islower than that of the transition touch electrode 14, so that thechannel impedance of the region where the transition touch electrode 14is positioned can be further reduced (e.g., the resistance of the regionwhere the transition touch electrode 14 is positioned can be furtherreduced). In addition, as shown in FIG. 24 and FIG. 26A, the firstconducting structure 23 extends along the second direction D2, and insuch a case, the first conducting structure 23 can enable the charges tobe uniformly distributed on the transition touch electrode 14 in thesecond direction D2, so that the first conducting structure 23 canassist the charges (the electric signal) in passing through thetransition touch electrode 14.

For example, as shown in FIG. 24, FIG. 26A and FIG. 26B, the firstconducting structure 23 and the connecting sub-electrode 31 (e.g., twoconnecting sub-electrodes 31) partially overlap in the directionperpendicular to the touch sensor 01, and two end portions of the firstconducting structure 23 in the second direction D2 are respectivelypositioned on both sides of the connecting sub-electrode 31 (e.g., twoconnecting sub-electrodes 31) in the second direction D2; and in such acase, the first conducting structure 23 assists the charges in passingthrough a region of the transition touch electrode 14 overlapping withthe connecting sub-electrode 31 in the direction perpendicular to thetouch sensor 01, so that the possibility of poor touch in the region ofthe transition touch electrode 14 overlapping with the connectingsub-electrode 31 in the direction perpendicular to the touch sensor 01can be reduced.

For example, the first conducting structure 23 can reduce thepossibility of poor touch caused by electrostatic discharge (e.g.,electrostatic breakdown).

For example, the first conducting structure 23 can be made of a metalmaterial, and the transition touch electrode 14 can be made of atransparent conducting material, so that the square resistance of thefirst conducting material 23 can be lower than that of the transitiontouch electrode 14.

For example, as shown in FIG. 24 to FIG. 27, the transition touchelectrode 14 is at least partially arranged between the opening region421 and a second portion 113; the transition touch electrode 14 has afirst side 143 away from the second portion 113 and a second side 144close to the second portion 113 in the first direction D1; and the firstconducting structure 23 is arranged at an edge of the transition touchelectrode 14 positioned on the first side 143. For example, by arrangingthe first conducting structure 23 at the edge of the transition touchelectrode 14 positioned on the first side 143 (i.e., the edge of thetransition touch electrode 14 away from the second portion 113),shielding of the first conducting structure 23 from light emitted by theactive display region of the display apparatus can be reduced in thecase that the first conducting structure 23 is made of a metal material,so that the display effect can be improved.

For example, as shown in FIG. 26A and FIG. 26B, the touch sensor 01further includes a second conducting structure 24, and the secondconducting structure 24 is at least arranged on the surface of a portionof the transition touch electrode 15 at least positioned between theopening region 421 and the transition touch electrode 14. For example,the second conducting structure 24 is in direct contact with the portionof the transition touch electrode 15 at least positioned between theopening region 421 and the transition touch electrode 14, i.e., thesecond conducting structure 24 is electrically connected with theportion of the transition touch electrode 15 at least positioned betweenthe opening region 421 and the transition touch electrode 14. Forexample, as shown in FIG. 24 and FIG. 26A, the second conductingstructure 24 is electrically connected (e.g., connected in parallel)with the portion of the transition touch electrode 15 at leastpositioned between the opening region 421 and the transition touchelectrode 14, so that the channel impedance (e.g., resistance) of aregion where the portion of the transition touch electrode 15 at leastpositioned between the opening region 421 and the transition touchelectrode 14 can be reduced.

For example, as shown in FIG. 24, FIG. 26A and FIG. 26B, the secondconducting structure 24 is arranged on the surface of the transitiontouch sub-electrode 152, at least partially surrounds the opening region421, and is electrically connected (e.g., connected in parallel) withthe transition touch sub-electrode 152, so that the second conductingstructure 24 can reduce the channel impedance (e.g., resistance) of aregion where the transition touch sub-electrode 152 is positioned, andimprove the charge conductivity of the region where the transition touchsub-electrode 152 is positioned.

For example, a square resistance of the second conducting structure 24is lower than that of the transition touch sub-electrode 152, so thatthe channel impedance (e.g., the resistance) of the region where thetransition touch sub-electrode 152 is positioned can be further reduced.For example, the second conducting structure 24 can be made of a metalmaterial, and the transition touch sub-electrode 152 can be made of atransparent conducting material, so that the square resistance of thesecond conducting structure 24 is lower than that of the transitiontouch sub-electrode 152.

For example, as shown in FIG. 24, the second conducting structure 24fully surrounds the opening region 421. For example, as shown in FIG. 24to FIG. 27, the transition touch sub-electrode 152 includes the inneredge 1522 and the outer edge 1523; and compared to the inner edge 1522of the transition touch sub-electrode 152, the second conductingstructure 24 is closer to the outer edge 1523 of the transition touchsub-electrode 152, and extends along the outer edge 1523 of thetransition touch sub-electrode 152.

For example, as shown in FIG. 24, FIG. 26A and FIG. 26B, the secondconducting structure 24 and the connecting sub-electrode 31 (e.g., twoconnecting sub-electrodes 31) partially overlap in the directionperpendicular to the touch sensor 01, and two end portions of the secondconducting structure 24 are respectively positioned on both sides of theconnecting sub-electrode 31 (e.g., two connecting sub-electrodes 31);and in such a case, the second conducting structure 24 assists thecharges in passing through a region of the transition touchsub-electrode 152 overlapping with the second conducting structure 24 inthe direction perpendicular to the touch sensor 01, so that thepossibility of poor touch in the region of the transition touchsub-electrode 152 overlapping with the second conducting structure 24 inthe direction perpendicular to the touch sensor 01 can be reduced. Forexample, the second conducting structure 24 can reduce the possibilityof poor touch caused by electrostatic discharge (e.g., electrostaticbreakdown).

It should be noted that the disclosure is not limited to the case thatthe second conducting structure 24 fully surrounds the opening region421, and in some examples, the second conducting structure 24 canpartially surround the opening region 421.

For example, as shown in FIG. 26A and FIG. 27, the first conductingstructure 23 and a portion of the second conducting structure 24adjacent to the first conducting structure 23 have corresponding bentstructures 231, respectively. For example, as shown in FIG. 26A and FIG.27, a portion of the second conducting structure 24 close to the firstconducting structure 23 and the first conducting structure 23 have thesame extending direction. For example, as shown in FIG. 26A and FIG. 27,the first conducting structure 23 includes a plurality of firstconducting line segments (e.g., straight line segments) sequentiallyconnected, and the second conducting structure 24 includes a pluralityof second conducting line segments (e.g., straight line segments)sequentially connected; the plurality of first conducting line segmentsand the plurality of second conducting line segments correspond one toone and are opposite to each other; and each of the plurality of firstconducting line segments and the corresponding second conducting linesegment have the same extending direction. For example, as shown in FIG.26A and FIG. 27, two adjacent (e.g., any two adjacent) first conductingline segments intersect with each other, and two adjacent (e.g., any twoadjacent) second conducting line segments intersect with each other; andthe first conducting line segment and second conducting line segmentthat are adjacent to each other (e.g., any two adjacent) are in parallelwith each other.

For example, as shown in FIG. 24, FIG. 26A and FIG. 27, the plurality offirst conducting line segments sequentially connected form a portion ofthe second conducting structure 24, and are positioned on one side ofthe center of the opening region 421 in the first direction D1 away fromthe center of the opening region 422.

FIG. 28 is a plane schematic diagram of a partial region REGE2 of thetouch sensor shown in FIG. 24. For example, as shown in FIG. 28, thetouch sensor 01 further includes a third conducting structure 25, andthe third conducting structure 25 is arranged on the surface of thetransition touch sub-electrode 151. For example, the third conductingstructure 25 is in direct contact with the transition touchsub-electrode 151. For example, as shown in FIG. 28, the thirdconducting structure 25 is electrically connected (e.g., connected inparallel) with the transition touch sub-electrode 151, so that thechannel impedance (e.g., resistance) of a region where the transitiontouch sub-electrode 151 is positioned can be reduced, and the chargeconductivity of the region where the transition touch sub-electrode 151is positioned can be improved.

For example, the square resistance of the third conducting structure 25is lower than that of the transition touch sub-electrode 151, so thatthe channel impedance (e.g., the resistance) of the region where thetransition touch sub-electrode 151 is positioned can be further reduced.For example, the second conducting structure 25 can be made of a metalmaterial, and the transition touch sub-electrode 151 can be made of atransparent conducting material, so that the square resistance of thesecond conducting structure 25 can be lower than that of the transitiontouch sub-electrode 151.

For example, as shown in FIG. 28, the transition touch sub-electrode 151is arranged on one side of the center of the opening region 422 close tothe opening region 421, and partially surrounds the opening region 422;the transition touch sub-electrode 151 includes a third side 1512 closeto the opening region 422 and a fourth side 1513 away from the openingregion 422; and the third conducting structure 25 extends at least alongan edge of the transition touch sub-electrode 151 positioned on thethird side 1512.

For example, as shown in FIG. 24 and FIG. 28, the transition touchsub-electrode 151 is electrically connected with a first portion 112 viathe jumper conductor wire 21. For example, the third conductingstructure 25 and the jumper conductor wire 21 are positioned in the sameelectrode layer (e.g., the second electrode layer (30), and are made ofthe same material; and for example, the third conducting structure 25and the jumper conductor wire 21 are formed in the same patterningprocess, so that the structure and the manufacturing process of thetouch sensor 01 can be simplified. For example, the third conductingstructure 25 and the jumper conductor wire 21 are directly connected.For example, the third conducting structure 25 and the jumper conductorwire 21 are of an integrated structure, i.e., the third conductingstructure 25 and the jumper conductor wire 21 are formed from the samematerial in the same patterning process. For example, there is nointerface between the third conducting structure 25 and the jumperconductor wire 21.

For example, the disclosure is not limited to the case that the thirdconducting structure 25 only extends along the edge of the transitiontouch sub-electrode 151 positioned on the third side 1512, and in someexamples, the third conducting structure 25 can also extend along anedge of the transition touch sub-electrode 151 positioned on the fourthside 1513.

FIG. 29A is a plane schematic diagram of a partial region REGE4 of thetouch sensor shown in FIG. 28; and FIG. 29B is a sectional schematicdiagram along an line EE′ shown in FIG. 29A.

For example, as shown in FIG. 28, FIG. 29A and FIG. 29B, the touchsensor 01 further includes a fourth conducting structure 26, and thefourth conducting structure 26 is arranged on the surface of thetransition touch electrode 16. For example, the fourth conductingstructure 26 is in direct contact with the transition touch electrode16.

For example, as shown in FIG. 28, FIG. 29A and FIG. 29B, the fourthconducting structure 26 is electrically connected (e.g., connected inparallel) with the transition touch electrode 16, and extends along atleast one of two opposite edges of the transition touch electrode 16 inthe first direction D1. For example, by arranging the fourth conductingstructure 26 on the surface of the transition touch electrode 16 andenabling the fourth conducting structure 26 to be electrically connected(e.g., connected in parallel) with the transition touch electrode 16,the channel impedance (e.g., resistance) of a region where thetransition touch electrode 16 is positioned can be reduced, and thecharge conductivity of the region where the transition touch electrode16 is positioned can be improved.

For example, a square resistance of the fourth conducting structure 26is lower than that of the transition touch electrode 16, so that thechannel impedance (e.g., the resistance) of the region where thetransition touch electrode 16 is positioned can be further reduced. Forexample, the fourth conducting structure 26 can be made of a metalmaterial, and the transition touch electrode 16 can be made of atransparent conducting material, so that the square resistance of thefourth conducting structure 26 can be lower than that of the transitiontouch electrode 16.

For example, as shown in FIG. 28, FIG. 29A and FIG. 29B, the transitiontouch electrode 16 includes a fifth side 166 close to the transitiontouch sub-electrode 151 and a sixth side 167 away from the transitiontouch sub-electrode 151 in the first direction D1; an edge of thetransition touch electrode 16 positioned on the fifth side 166 includesa plurality of first protruding portions 161 protruding towards thetransition touch sub-electrode 151; an edge of the transition touchelectrode 16 positioned on the sixth side 167 includes a plurality ofsecond protruding portions 162 protruding towards the transition touchsub-electrode 152; the edge of the transition touch sub-electrode 151positioned on the fourth side 1513 (i.e., the edge close to thetransition touch electrode 16) includes a plurality of first sunkportions 1511; the edge of the transition touch sub-electrode 152 closeto the transition touch electrode 16 includes a plurality of second sunkportions 1521; and the plurality of first protruding portions 161 arecorrespondingly arranged in the plurality of first sunk portions 1511,and the plurality of second protruding portions 162 are correspondinglyarranged in the plurality of second sunk portions 1521.

For example, as shown in FIG. 28, FIG. 29A and FIG. 29B, the fourthconducting structure 26 includes a first conducting sub-structure 261and a second conducting sub-structure 262; the first conductingsub-structure 261 extends along the edge of the transition touchelectrode 16 positioned on the fifth side 166, and includes a pluralityof second bent structures 2611; the second conducting sub-structure 262extends along the edge of the transition touch electrode 16 positionedon the sixth side 167, and includes a plurality of third bent structures2621; and the plurality of second bent structures 2611 arecorrespondingly arranged in the plurality of first sunk portions 1511,and the plurality of third bent structures 2621 are correspondinglyarranged in the plurality of second sunk portions 1521.

For example, as shown in FIG. 28, FIG. 29A and FIG. 29B, the firstconducting sub-structure 261 and the second conducting sub-structure 262respectively and partially overlap with the connecting sub-electrode 31(e.g., two connecting sub-electrodes 31) in the direction perpendicularto the touch sensor 01, two end portions of the first conductingsub-structure 261 in the second direction D2 are respectively positionedon both sides of the connecting sub-electrode 31 (e.g., two connectingsub-electrodes 31) in the second direction D2, and two end portions ofthe second conducting sub-structure 262 in the second direction D2 arerespectively positioned on both sides of the connecting sub-electrode 31(e.g., two connecting sub-electrodes 31) in the second direction D2; insuch a case, the first conducting sub-structure 261 and the secondconducting sub-structure 262 assist the charges in passing through aregion of the transition touch electrode 16 overlapping with the firstconducting sub-structure 261 and the second conducting sub-structure 262in the direction perpendicular to the touch sensor 01, so that thepossibility of poor touch in the region of the transition touchelectrode 16 overlapping with the first conducting sub-structure 261 andthe second conducting sub-structure 262 in the direction perpendicularto the touch sensor 01 can be reduced. For example, the first conductingsub-structure 261 and the second conducting sub-structure 262 can reducethe possibility of poor touch caused by electrostatic discharge (e.g.,electrostatic breakdown).

For example, the first conducting structure 23, the second conductingstructure 24, the third conducting structure 25 and the fourthconducting structure 26 are made of the same material (e.g., a metalmaterial) and formed in the same patterning process, so that thestructure and the manufacturing process of the touch sensor 01 can besimplified. For example, the first conducting structure 23, the secondconducting structure 24, the third conducting structure 25 and thefourth conducting structure 26 are positioned in the same electrodelayer, and in direct contact with the same film layer.

For example, the jumper conductor wire 21, the jumper conductor wire 22,the first conducting structure 23, the second conducting structure 24,the third conducting structure 25 and the fourth conducting structure 26are made of the same material (e.g., a metal material) and formed in thesame patterning process, so that the structure and the manufacturingprocess of the touch sensor 01 can be further simplified, and theincrease of manufacturing cost of the touch sensor 01 is avoided. Forexample, the jumper conductor wire 21, the jumper conductor wire 22, thefirst conducting structure 23, the second conducting structure 24, thethird conducting structure 25 and the fourth conducting structure 26 areall positioned in the second electrode layer 30 shown in FIG. 13. Forexample, the jumper conductor wire 21, the jumper conductor wire 22, thefirst conducting structure 23, the second conducting structure 24, thethird conducting structure 25 and the fourth conducting structure 26 areall in contact with the same film layer (e.g., all in contact with theinsulating layer 35 shown in FIG. 13).

For example, as shown in FIG. 24 to FIG. 29A, the jumper conductor wire21, the jumper conductor wire 22, the first conducting structure 23, thesecond conducting structure 24, the third conducting structure 25 andthe fourth conducting structure 26 are all implemented as conductors,but the embodiments of the present disclosure are not limited thereto.For example, line widths of the above-mentioned conductors are within arange of 3 microns to 8 microns (e.g., 5 microns).

For example, at least one (e.g., all) of the first conducting structure23, the second conducting structure 24, the third conducting structure25 and the fourth conducting structure 26 can be implemented as a sheetmetal electrode structure. For example, an average width of the sheetmetal electrode structures is greater than 30 microns (e.g., 50 microns,100 microns or 200 microns). For example, by implementing at least oneof the first conducting structure 23, the second conducting structure24, the third conducting structure 25 and the fourth conductingstructure 26 as the sheet metal electrode structure, the channelimpedance of the region where the transition touch electrodecorresponding to at least one of the first conducting structure 23, thesecond conducting structure 24, the third conducting structure 25 andthe fourth conducting structure 26 is positioned can be further reduced,and the charge conductivity of the region where the transition touchelectrode corresponding to at least one of the first conductingstructure 23, the second conducting structure 24, the third conductingstructure 25 and the fourth conducting structure 26 is positioned can befurther improved, so that the possibility of poor touch, caused byelectrostatic discharge (e.g., electrostatic breakdown), in the regionwhere the transition touch electrode corresponding to at least one ofthe first conducting structure 23, the second conducting structure 24,the third conducting structure 25 and the fourth conducting structure 26is positioned can be further reduced, and the reliability of the regionwhere the transition touch electrode corresponding to at least one ofthe first conducting structure 23, the second conducting structure 24,the third conducting structure 25 and the fourth conducting structure 26is positioned can be promoted.

In an example, the second conducting structure 24 may be arranged on anoverall surface of the transition touch sub-electrode 152, and is of thesame or similar shape with the transition touch sub-electrode 152; thethird conducting structure 25 can be arranged on the overall surface ofthe transition touch sub-electrode 151, and is of the same or similarshape with the transition touch sub-electrode 151; and the fourthconducting structure 26 can be arranged on the overall surface of thetransition touch electrode 16, and is of the same or similar shape withthe transition touch electrode 16.

For example, the first conducting structure 23 may be arranged on theoverall surface of the transition touch electrode 14, and is of the sameor similar shape with the transition touch electrode 14. For anotherexample, the transition touch electrode 14 includes a first portioncorresponding to the active display region of the display apparatus 03and a second portion corresponding to the inactive display region (referto FIG. 24) of the display apparatus 03; and the first conductingstructure 23 can be arranged on the overall surface of the secondportion of the transition touch electrode 14. For example, as shown inFIG. 24, the active display region of the display apparatus 03 surrounds(e.g., fully surrounds) the inactive display region of the displayapparatus 03. For example, as shown in FIG. 24, the inactive displayregion of the display apparatus 03 corresponds to the opening region421, the opening region 422 and a region between the opening region 421and the opening region 422, and surrounds a transitional region of theopening region 421 and the opening region 422 and a region for arrangingthe jumper conductor wires 21 and 22 and the first conducting structure23. For example, the inactive display region of the display apparatus 03is not used for forming the display image.

It should be noted that although the touch sensor 01 of the displayapparatus 03 shown in FIG. 24 to FIG. 28, FIG. 29A, FIG. 29B and otherdrawings is simultaneously provided with the first conducting structure23, the second conducting structure 24, the third conducting structure25 and the fourth conducting structure 26, the embodiments of thepresent disclosure are not limited thereto. For example, according topractical application demands, the touch sensor 01 of the displayapparatus 03 shown in FIG. 24 to FIG. 28, FIG. 29A, FIG. 29B and otherdrawings may also be provided with any one, any two or any three of thefirst conducting structure 23, the second conducting structure 24, thethird conducting structure 25 and the fourth conducting structure 26.

It should be noted in that in the touch sensor 01 provided by at leastone embodiment of the present disclosure, the disclosure is not limitedto the case that the distance between the first position 1452 and thesecond position 1453 is less than the maximum width of at least one ofthe plurality of second touch sub-electrodes 121 in the first directionD1.

In some examples, the touch sensor 01 includes the opening region 421, aplurality of first touch electrodes 11, a plurality of second touchelectrodes 12 and the conducting structure 23. The center 012 of theopening region 421 and the center 011 of the touch sensor 01 do notcoincide; the plurality of first touch electrodes 11 respectively extendalong the first direction D1, and at least one of the plurality of firsttouch electrodes 11 includes a plurality of first touch sub-electrodes111 arranged side by side in the first direction D1 and electricallyconnected with each other; the plurality of second touch electrodes 12respectively extend along the second direction D2 intersecting with thefirst direction D1, and at least one of the plurality of second touchelectrodes 12 includes a plurality of second touch sub-electrodes 121arranged side by side in the second direction D2 and electricallyconnected with each other; the plurality of first touch electrodes 11are arranged side by side along the second direction D2, and theplurality of second touch electrodes 12 are arranged side by side alongthe first direction D1; the plurality of first touch sub-electrodes 111and the plurality of second touch sub-electrodes 121 together at leastpartially surround the opening region 421; each of one group of secondtouch electrodes 12 in the plurality of second touch electrodes 12further includes the transition touch electrode 14; the transition touchelectrode 14 extends in the second direction D2, and partially surroundsthe opening region 421 along the second direction D2; the touch sensor01 includes the first region 411, the second region 412 and the thirdregion 413 which are sequentially laid out in the second direction D2;at least part of the transition touch electrode 14 and the openingregion 421 are positioned in the second region; the resistance of thetransition touch electrode 14 is higher than that of the second touchsub-electrode 121 in the first region 411; and the conducting structure23 is positioned on the surface of the transition touch electrode 14, atleast partially surrounds the edge of the opening region 421, and iselectrically connected with the transition touch electrode 14.

For example, the area of the first touch sub-electrode 111 in the firstregion 411 is less than that of the first touch sub-electrode 111 in thethird region 413, or the area of the second touch sub-electrode 121 inthe first region 411 is less than that of the second touch sub-electrode121 in the third region 413.

For example, the resistance of the transition touch electrode 14 ishigher than that of the second touch sub-electrode 121 in the thirdregion 413.

In some examples, the touch sensor 01 includes a plurality of firsttouch electrodes 11, a plurality of second touch electrodes 12 and acrack blocking ring 2. The plurality of first touch electrodes 11respectively extend along the first direction D1, and at least one ofthe plurality of first touch electrodes 11 includes a plurality of firsttouch sub-electrodes 111 arranged side by side in the first direction D1and electrically connected with each other; the plurality of secondtouch electrodes 12 respectively extend along the second direction D2intersecting with the first direction D1, and at least one of theplurality of second touch electrodes 12 includes a plurality of secondtouch sub-electrodes 121 arranged side by side in the second directionD2 and electrically connected with each other; the plurality of firsttouch electrodes 11 are arranged side by side along the second directionD2, and the plurality of second touch electrodes 12 are arranged side byside along the first direction D1; the touch sensor has the openingregion 421, and a transitional region 424 and a touch functional region423 which are sequentially laid out from the center of the openingregion 421 to the outside; the center of the opening region 421 and thecenter of the touch sensor do not coincide; the touch functional region423 surrounds the transitional region 424; the plurality of first touchelectrodes 11 and the plurality of second touch electrodes 12 arepositioned in the touch functional region 423; the plurality of firsttouch sub-electrodes 111 and the plurality of second touchsub-electrodes 121 together at least partially surround the openingregion 421; and the crack blocking ring 27 is positioned in thetransitional region 424 and at least partially surrounds the openingregion 421. For example, by arranging the crack blocking ring 27 in thetransitional region 424 of the touch sensor 01, the possibility thatcracks formed by perforating the display apparatus extend to the touchfunctional region of the touch sensor 01 can be reduced, so that thepossibility of poorness of the touch sensor 01 caused by the cracks canbe reduced. Exemplary illustration will be carried out below inconnection with FIG. 30 to FIG. 36, FIG. 26A and FIG. 26B.

FIG. 30 is a related schematic diagram of the partial region REG1included in the touch sensor 01 of the display apparatus 03 shown inFIG. 4; FIG. 31A is a plane schematic diagram of a partial region REGR1of the touch sensor 01 shown in FIG. 30; FIG. 32 is another planeschematic diagram of the partial region REGR1 of the touch sensor 01shown in FIG. 30; and FIG. 33 is a plane schematic diagram of a portionof the crack blocking ring 27 provided by at least one embodiment of thepresent disclosure.

For example, as shown in FIG. 30, the touch sensor 01 has the openingregion 421, the opening region 422, the transitional region 424, atransitional region 425 and the touch functional region 423. Forexample, as shown in FIG. 30, the transitional region 424 and the touchfunctional region 423 are sequentially laid out from the center of theopening region 421 to the outside; the touch functional region 423surrounds the transitional region 424; and the transitional region 424surrounds the opening region 421. For example, the touch functionalregion 423 and the transitional region 424 are spaced from each other.For example, the touch functional region 423 and the transitional region424 are spaced by an etching groove (which is not shown in FIG. 30, withreference to FIG. 26B) positioned between the touch functional region423 and the transitional region 424.

For example, the touch functional region 423 is a region for arrangingthe touch electrode and the jumper conductor wire. For example, as shownin FIG. 30, the plurality of first touch electrodes 11, the plurality ofsecond touch electrodes 12, the transition touch electrode 14, thetransition touch electrode 15, the transition touch electrode 16, thejumper conductor wire 21 and the jumper conductor wire 22 are positionedin the touch functional region 423. For example, in the case that thetouch sensor 01 is also provided with the first conducting structure 23,the second conducting structure 24, the third conducting structure 25and the fourth conducting structure 26, the first conducting structure23, the second conducting structure 24, the third conducting structure25 and the fourth conducting structure 26 are respectively arranged onthe corresponding transition touch electrodes, and thus, as shown inFIG. 30, FIG. 31A, FIG. 26B and FIG. 29B, the first conducting structure23, the second conducting structure 24, the third conducting structure25 and the fourth conducting structure 26 are also arranged in the touchfunctional region 423.

For example, as shown in FIG. 26B and FIG. 30 to FIG. 33, the crackblocking crack 27 is positioned in the transitional region 424 and atleast partially surrounds (e.g., fully surrounds or partially surrounds)the opening region 421. for example, by arranging the crack blockingring 27 at least partially surrounding the opening region 421 in thetransitional region 424, the cracks caused by formation (laser cutting)of the opening region 421, can be inhibited from entering the touchfunctional region 423, so that poor touch caused by the crack can beinhibited.

For example, the crack blocking ring 27 is a metal ring. For example,metal has the excellent heat conduction characteristic, and by using themetal ring as the crack blocking ring 27, when laser perforation (lasercutting) is carried out on the display apparatus 03, a heat stresscaused by laser can be reduced, and thus, the possibility of forming thecracks around the opening region 421 when laser perforation (lasercutting) is carried out on the display apparatus 03 can be reduced, sothat an inhibiting effect of the crack blocking ring 27 on the crackscan be improved. For example, the metal has the excellent ductilitycharacteristic, and thus, by using the metal ring as the crack blockingring 27, the possibility that the cracks are further expanded in asubsequent laminating process can be reduced, so that the inhibitingeffect of the crack blocking ring 27 on the cracks can be improved.

It should be noted that the crack blocking ring 27 shown in FIG. 30 isused for showing an approximate position of the crack blocking ring 27,but not used for limiting a specific position or a specific structure ofthe crack blocking ring 27. For example, examples of the specificposition or the specific structure of the crack blocking ring 27 canrefer to FIG. 31A to FIG. 33.

For example, as shown in FIG. 31A, an inner edge 272 of the crackblocking ring 27 surrounds the edge 4211 of the opening region 421, butthe embodiments of the present disclosure are not limited thereto. Insome examples, as shown in FIG. 32, the crack blocking ring 27 coincideswith the edge 4211 of the opening region 421.

For example, as shown in FIG. 32, before the opening region 421 isformed (i.e., before perforation), a cutting line (i.e., correspondingto the edge 4211 of the opening region 421) surrounds an inner edge of aring for forming the crack blocking ring 27; and after the openingregion 421 is formed (i.e., after perforation), a portion of the ringpositioned within the cutting line for forming the crack blocking ring27 is cut off, and in such a case, the crack blocking ring 27 coincidewith the edge 4211 of the opening region 421.

For example, the crack blocking ring 27 is a conducting ring, the crackblocking ring 27 has at least one fracture 271, and each of at least onefracture 271 has a tip; in such a case, electrostatic charges in aregion of the touch sensor 01 corresponding to the crack blocking ring27 can be discharged via the tip included in each of at least onefracture 271, so that the possibility of poor touch function caused byelectrostatic breakdown in the active touch region around the openingregion 421 can be reduced. For example, at least one fracture 271 is ofa lightning shape, so that the electrostatic charges in the region ofthe touch sensor 01 corresponding to the crack blocking ring 27 can bedischarged better. For example, the electrical conductivity of the crackblocking ring 27 is superior to those of the materials for forming thefirst touch sub-electrode 111 and the second touch sub-electrode 121,and in such a case, the electrostatic charges in the region of the touchsensor 01 corresponding to the crack blocking ring 27 can be dischargedbetter.

For example, the crack blocking ring 27 has light shielding or lightabsorption performance, and in such a case, the crack blocking ring 27can also reduce light emitted by a display panel and leaked into theopening region 421; and for example, in the case that a sensor (e.g., animaging sensor) is arranged in the opening region 421, light incident toa light collecting surface of the sensor (e.g., the imaging sensor) canbe reduced, so that a signal-to-noise ratio of an output signal (e.g.,an image) of the sensor (e.g., the imaging sensor) can be increased.

For example, the crack blocking ring 27 is the metal ring. For example,the metal has the excellent electrical conductivity, and thus, by usingthe metal ring as the crack blocking ring 27, the electrostatic chargesin the region of the touch sensor 01 corresponding to the crack blockingring 27 can be discharged better; and the metal has light shieldingperformance, and thus, by using the metal ring as the crack blockingring 27, the signal-to-noise ratio of the output image of the imagingsensor can also be increased.

For example, a ring width of the crack blocking ring 27 is greater thantwice (e.g., six times, ten times, twenty times and thirty times) of theline width of the conductor (e.g., the jumper conductor wire 21 and thejumper conductor wire 21) included in the touch sensor 01. For example,the ring width of the crack blocking ring 27 is equal to 30 microns, 50microns, 100 microns or 150 microns, but the embodiments of the presentdisclosure are not limited thereto. For example, by making the ringwidth of the crack blocking ring 27 greater than six times of the linewidth of the conductor (e.g., the jumper conductor wire 21 and thejumper conductor wire 21) included in the touch sensor 01, the crackblocking ability of the crack blocking ring 27 can be improved.

For example, the ring width of the crack blocking ring 27 is 0.004millimeter to 0.9 millimeter. For example, as shown in FIG. 31A, thecrack blocking ring 27 has at least two fractures 271; and at least twofractures 271 separate the crack blocking ring 27 into at least twoblocking ring sub-portions 273 in a circumferential direction of thecrack blocking ring 27.

FIG. 31B is an enlarged diagram of a partial region REG_R shown in FIG.30. It should be noted that for clarity, FIG. 31B carries out rotationtreatment on the partial region REG_R shown in FIG. 30. For example, asshown in FIG. 31B, the distance Rd between adjacent edges of adjacentend portions of the at least two blocking ring sub-portions 273 in thecircumferential direction of the crack blocking ring 27 is 0.008millimeter to 0.030 millimeter. For example, as shown in FIG. 31B, theend portion of each of the at least two blocking ring sub-portions 273in the circumferential direction of the crack blocking ring 27 has astep structure 2731. For example, the size of the step surface 2732 ofthe step structure 2731 in the circumferential direction of the crackblocking ring 27 is 0.004 millimeter to 0.015 millimeter.

For example, as shown in FIG. 31A and FIG. 32, the touch sensor 01further includes a crack blocking ring 28 at least partially surroundingthe crack blocking ring 27 and separated from the crack blocking ring27, and the crack blocking ring 28 is positioned in the transitionalregion 424. For example, by enabling the touch sensor to further includethe crack blocking ring 28 surrounding the crack blocking ring 27 andseparated from the crack blocking ring 27, the possibility that thecracks formed when perforation is carried out on the display apparatusextend to the touch functional region of the touch sensor 01 can befurther reduced, so that the possibility of poorness of the touch sensor01 caused by the cracks can be further reduced.

For example, as shown in FIG. 31A and FIG. 32, the crack blocking ring28 has at least one fracture 281, and at least one fracture 281 includesa tip. For example, the crack blocking ring 28 is a conducting ring(e.g., a metal ring). For example, by enabling the crack blocking ring28 to be the conducting ring and enabling the crack blocking ring 28 tohave at least one fracture 281, electrostatic charges accumulated in aregion of the touch sensor 01 corresponding to the crack blocking ring28 can be discharged via the tip included in the fracture 281, so thatthe possibility of poor touch function caused by electrostatic breakdownin the active touch region around the opening region 421 can be furtherreduced.

For example, at least one fracture 281 is of a lightning shape, so thatthe electrostatic charges in the region of the touch sensor 01corresponding to the crack blocking ring 28 can be discharged better.For example, the electrical conductivity of the crack blocking ring 28is superior to those of the materials for forming the first touchsub-electrode 111 and the second touch sub-electrode 121, and in such acase, the electrostatic charges in the region of the touch sensor 01corresponding to the crack blocking ring 28 can be discharged better.

For example, as shown in FIG. 31A and FIG. 32, the fracture 271 and thefracture 281 are staggered mutually; and in such a case, the possibilitythat the cracks extend to the touch functional region of the touchsensor 01 via the fracture 271 and the fracture 281 can be avoided, sothat the possibility of poorness of the touch sensor 01 caused by thecracks can be further reduced.

For example, as shown in FIG. 31A, a ring width of the crack blockingring 28 is equal to that of the crack blocking ring 27, but theembodiments of the present disclosure are not limited thereto. Foranother example, as shown in FIG. 32, the ring width of the crackblocking ring 28 is less than that of the crack blocking ring 27.

For example, the ring width of the crack blocking ring 28 is 0.004millimeter to 0.9 millimeter. For example, the distance between an inneredge of the crack blocking ring 28 and an outer edge of the crackblocking ring 27 in a radial direction of the crack blocking ring 27 is0.004 millimeter to 0.1 millimeter. For example, as shown in FIG. 31A,the crack blocking ring 28 has at least two fractures 281; and at leasttwo fractures 281 separate the crack blocking ring 28 into at least twoblocking ring sub-portions 283 in a circumferential direction of thecrack blocking ring 28. For example, as shown in FIG. 31A, an endportion of each of the at least two blocking ring sub-portions 283 inthe circumferential direction of the crack blocking ring 28 has a stepstructure.

For example, as shown in FIG. 31A to FIG. 33, the edge 4211 of theopening region 421 is of a circle shape, the crack blocking ring 27 andthe crack blocking ring 28 integrally are of a circular ring shape, butthe embodiments of the present disclosure are not limited thereto; andfor example, according to practical application demands, the edge 4211of the opening region 421 is of a racetrack shape or other applicableshapes, and the crack blocking ring 27 and the crack blocking ring 28can also integrally be of a racetrack shape or other applicable shapes.

It should be noted that the disclosure is not limited to the case thatone or two crack blocking rings are arranged in the transitional region424, and according to practical application demands, three or otherapplicable numbers of crack blocking rings can also be arranged in thetransitional region 424.

FIG. 34 is a plane schematic diagram of a partial region REGR2 of thetouch sensor 01 shown in FIG. 30; FIG. 35 is another plane schematicdiagram of the partial region REGR2 of the touch sensor 01 shown in FIG.30; and FIG. 36 is a plane schematic diagram of a partial region REGR3of the touch sensor 01 shown in FIG. 35.

For example, as shown in FIG. 30, FIG. 34 and FIG. 35, the transitionalregion 425 and the touch functional region 423 are sequentially laid outfrom the center of the opening region 422 to the outside. For example,as shown in FIG. 30, FIG. 34 and FIG. 35, the touch sensor 01 furtherincludes a crack blocking ring 29 positioned in the transitional region425. For example, as shown in FIG. 30, FIG. 34 and FIG. 35, the edge ofthe opening region 422 is of a racetrack shape; the crack blocking ring29 is at least part of the racetrack shape, but the embodiments of thepresent disclosure are not limited thereto; and for example, accordingto practical application demands, the edge of the opening region 422 isof a circle shape or other applicable shapes, and the crack blockingring 29 can also integrally be of a circular ring shape or otherapplicable shapes.

For example, the crack blocking ring 29 is a conducting ring (e.g., ametal ring); as shown in FIG. 30, FIG. 34 and FIG. 35, the crackblocking ring 29 includes at least one fracture 291, and at least onefracture 291 has a tip; and in such a case, the electrostatic charges ina region of the touch sensor 01 corresponding to the crack blocking ring29 can be discharged via the tip included in the fracture 291, so thatthe possibility of poor touch function caused by electrostatic breakdownin the active touch region around the opening region 421 can be furtherreduced. For example, at least one fracture 291 is of a lightning shape,so that the electrostatic charges in the region of the touch sensor 01corresponding to the crack blocking ring 29 can be discharged better.For example, the electrical conductivity of the crack blocking ring 29is superior to those of the materials for forming the first touchsub-electrode 111 and the second touch sub-electrode 121, and in such acase, the electrostatic charges in the region of the touch sensor 01corresponding to the crack blocking ring 29 can be discharged better.For example, the crack blocking ring 29 can have shielding or lightblocking performance, and in such a case, the crack blocking ring 29 canalso reduce the light emitted by the display panel and leaked into theopening region 422; and for example, in the case that a sensor (e.g., animaging sensor) is arranged in the opening region 422, light incident toa light collecting surface of the sensor (e.g., the imaging sensor) canbe reduced, so that a signal-to-noise ratio of an output signal (e.g.,an image) of the sensor (e.g., the imaging sensor) can be increased.

For example, as shown in FIG. 30, FIG. 34 and FIG. 35, the crackblocking ring 29 partially surrounds the opening region 422, and isarranged in parallel with the transition touch sub-electrode 151 in thefirst direction D1.

In an example, as shown in FIG. 34, the crack blocking ring 29 and thetransition touch sub-electrode 151 do not overlap in the seconddirection D2. In another example, as shown in FIG. 35, the crackblocking ring 29 is partially arranged between the opening region 422and the transition touch sub-electrode 151, and the crack blocking ring29 and the transition touch sub-electrode 151 at least partially overlapin the second direction D2.

For example, as shown in FIG. 30 and FIG. 34 to FIG. 36, the touchsensor 01 further includes a crack blocking ring 292 positioned in thetransitional region 425 and at least partially surrounding the crackblocking ring 29. For example, as shown in FIG. 30, FIG. 34 and FIG. 35,the crack blocking ring 292 integrally is a racetrack-shaped ring. Forexample, as shown in FIG. 30, FIG. 34 and FIG. 35, the crack blockingring 292 has a fracture 293, and the fracture 293 and the fracture 291correspond to each other. For example, the crack blocking ring 292 is aconducting ring (e.g., a metal ring). For example, ring widths of thecrack blocking ring 29 and the crack blocking ring 292 are 0.004millimeter to 0.9 millimeter. For example, a distance between an inneredge of the crack blocking ring 292 and an outer edge of the crackblocking ring 29 is 0.004 millimeter to 0.1 millimeter.

For example, as shown in FIG. 30 and FIG. 34 to FIG. 36, in a radialdirection of the opening region 422, at least one jumper conductor wire21 is positioned between the jumper conductor wire 22 and the crackblocking ring 29. For example, as shown in FIG. 30 and FIG. 34 to FIG.36, in the radial direction of the opening region 422, at least onejumper conductor wire 21 is positioned between the jumper conductor wire22 and the crack blocking ring 292.

For example, the crack blocking ring (e.g., at least one of the crackblocking ring 27, the crack blocking ring 28, the crack blocking ring 29and the crack blocking ring 292) and the jumper conductor wire (e.g., atleast one of the jumper conductor wire 21 and the jumper conductor wire22) are positioned in the same electrode layer (e.g., the secondelectrode layer 30), and are in direct contact with the same film layer.

For example, the crack blocking ring (e.g., at least one of the crackblocking ring 27, the crack blocking ring 28, the crack blocking ring 29and the crack blocking ring 292) and the jumper conductor wire (e.g., atleast one of the jumper conductor wire 21 and the jumper conductor wire22) are made of the same material (e.g., the metal material) and formedin the same patterning process, so that the structure and themanufacturing process of the touch sensor 01 can be further simplified,and the increase of manufacturing cost of the touch sensor 01 isavoided.

Several points below need to be illustrated.

(1) It is not limited to the case that one or two crack blocking ringsare arranged in the transitional region 425, and according to practicalapplication demands, three or other applicable numbers of crack blockingrings can also be arranged in the transitional region 425.

According to practical application demands, thecrack blocking ring can also be not arranged in at least one of thetransitional region 424 and the transitional region 425.

For example, according to practical applicationdemands, for the touch sensor 01, only the first region of the touchsensor 01 may be optimized, but the jumper conductor wire, thetransition touch electrode, the conducting structure and the crackblocking ring are not arranged; and for another example, according topractical application demands, for the touch sensor 01, the first regionof the touch sensor 01 may be not optimized, but at least part (e.g.,one to four) of the jumper conductor wire, the transition touchelectrode, the conducting structure and the crack blocking ring arearranged.
